Abstract Kink defects in nanocellulose are ubiquitous yet associated questions remain open regarding the unclear
microstructure-mechanical property relationship. Various kink patterns without molecular-scale resolution
result in bemusements of how nanocellulose forms different kinks and what the fundamental mechanisms
of reversible and irreversible kinks are. In our atomic force microscopy images of mechanically treated
cellulose nanofibrils, bent nanofibrils usually exhibit small curvatures while kinked nanofibrils feature
sharp bends, in which kinks are conspicuous due to their promiscuous configurations. To identify the
nanomechanics of incipient kink defects formed in nanocellulose, molecular dynamics simulations of
cellulose nanocrystals (CNCs) under curvature-dependent bending are subsequently carried… More >

Abstract A simulation of reheating furnace in a steel production line where the steel billets are heated from room
temperature up to 1200 ˚C, is carried out using a novel meshless solution procedure. The reheating of the
steel billets before the continuous hot-rolling process should be employed to dissolve alloying elements as
much as possible and redistribute the carbon. In this work, governing equations are solved by the local radial
basis function collocation method (LRBFCM) in a strong form with explicit time-stepping. The solution of
the diffusion equations for the temperature and carbon concentration fields is formulated on a twodimensional slice.… More >

Abstract In this research, a rolling simulation system based on a novel meshless solution procedure is upgraded
considering casting defects in the material model. The improved model can predict the final stage of the
defects after multi-pass rolling. The casted steel billet that enters the rolling mill arrives with casting defects.
Those defects may be porosity due to the shrinkage and cavity or micro-cracks near the surface due to hot
tearing. In this work, porosity is considered the main defect source since it can easily be determined
experimentally. The damage theory develops a damaged stiffness matrix with a scalar damage value.… More >

Abstract The phase-field fracture (PFF) approach has achieved great triumphs in modeling quasi-static fracture.
Nevertheless, its reliability in serving dynamic fractures still leaves something to be desired, such as the
prediction of the limiting crack velocity. Using a pre-strained fracture configuration, we discovered a
disturbing phenomenon that the crack limiting speed identified by the dynamic PFF model is not related to
the specific material, which seriously deviates from the experimental observation. To ascertain the truth,
we first ruled out the correlation between the limiting crack velocity on the phase-field characteristic scale
and external loading. Afterward, by switching between different crack surface… More >

Abstract Instability in dynamic fracture suppresses crack velocity from reaching theoretical limit predicted by the
classical linear elastic fracture mechanics (LEFM). In thin systems, crack can accelerate to near the
theoretical limiting velocity without micro-branching instability. A dynamic oscillatory instability is
observed at such extreme crack speed. This sinusoidal oscillation was further found to be governed by
intrinsic nonlinear scale. Using a dynamic phase-field model (PFM) with no attenuation of wave speed, we
successfully reproduce the oscillations in the framework of non-linear deformation. The used PFM model
based on Griffith's theory and derived from the nonconservative Lagrange's equation. To deal with… More >

Abstract Nuclear fuel cladding tubes have a outer diameter about 10 mm with a wall thickness about 0.5 mm. Their
mechanical properties hence cannot be researched using standard test methods. In this study, small punch
test (SPT) was developed to research the mechanical properties of nuclear fuel cladding tubes. Instead of
plate SPT specimen, tube specimen was used to research fracture toughness and creep properties. Fninite
elment simulation based on GTN model was used to verify the proposed method. Results indicated that the
tube specimen with a noth can be sufficiently to research fracture toughness. The small punch creep test

Abstract Fracture analysis is a problem playing a fundamental role in the fields of Aerospace Mechanics and
Structural Mechanics. The paper deals with the analysis of the most essential among the fracture problems:
the one-dimensional crack in a double cantilever beam. The report presents a reliable analytical method to
correctly partition the energy release rates into pure fracture modes, appliable to both isotropic and
composite beams with clearly known mechanical properties, subject to shearing or bending loads. The
adopted strategy is based on the Timoshenko’s kinematic model and exploits the theoretical definition of
the I and II pure energy release rate… More >

Abstract The paper presents a novel fast calculation method for broadband Electromagnetic Scattering analysis. In
this work, the isogeometric boundary element method is used to solve Helmholtz equations for the
electromagnetic scattering problems. The non-uniform rational B-splines are employed to construct
structural geometries and discretize electric and magnetic field integral equations [1,2]. To avoid timeconsuming multi-frequency calculations, the series expansion method is used to decouple the frequencydependent terms from the integrand in the boundary element method [3,4]. The second-order Arnoldi
(SOAR) method is applied to construct a reduced-order model that retains the essential structures and key
properties of the original model… More >

Abstract Alkaline water electrolysis system for hydrogen production has the characteristics of complex structure,
fault coupling and state nonlinearity, coupled with the restriction by many factors such as data acquisition

alkaline water electrolysis system, a digital twin-driven predictive maintenance method is put forward to
achieve the real-time monitoring of operation status and prediction of remaining useful life. In the study, a

Abstract Acoustic radiation and propagation characteristics of underwater elastic structures are an organic whole,
which should be considered comprehensively. Based on the three-dimensional sono-elasticity theory of
ships, the integrated calculation method of acoustic radiation and propagation in ocean environment is
realized by using the simple source boundary integral equation. The correctness and accuracy of the method
are verified by a series of examples. Based on the domestic supercomputer platform, the parallel
transformation of the algorithm is completed, and the two-level multi-core parallel is realized, which greatly
improves the computing efficiency. The application of acoustic radiation calculation in composite structures

Abstract Two or multiple phases commonly occur as fluid mixture in petroleum industry, where oil, gas and water
are often produced and transported together. As a result, petroleum reservoir engineers spent great efforts
in the development and production of oil and gas reservoirs by conducting and interpolating the simulation
of multiphase flows in porous geological formation. Meanwhile, environmental scientists use subsurface
flow and transport models to investigate and compare for example various schemes to inject and store CO2
in subsurface geological formations, such as depleted reservoirs and deep saline aquifers. In this work, we

Abstract The engineering application prospects of soft materials in key areas such as aerospace and life science have
stimulated extensive research interests in the academic community. An important topic here is to predict
the service and failure behavior of such materials. Although considerable progress has been made, realworld application scenarios usually involve bi-material as well as multi-material adhesion, with cohesive
interface rupture as the main failure vehicle. Inconsistent asymptotic solutions in the context of large
deformations pose obstacles to the establishment of a theoretical framework for the interface fracture
problem in soft materials [1]. Driven by both engineering and academia, numerical… More >

Abstract External photo-stimuli on heterojunctions commonly induce an electric potential gradient across the
interface therein, such as photovoltaic effect, giving rise to various present-day technical devices. In contrast,
in-plane potential gradient along the interface has been rarely observed. Here we show that moving a light
beam at the semiconductor-water interface, i.e. creating a moving boundary of electrical double layers
between the illuminated and dark regions, induce a potential gradient along the semiconductor. It is
attributed to the following movement of a charge packet in the vicinity of the silicon surface, whose
formation is driven by a built-in electrical field associated with… More >

Abstract Wind energy is one of the most promising renewable energies in the world. To generate more electricity,
the wind turbines are getting larger and larger in recent decades [1]. With the wind turbine size growing,
the length of the blade is getting slender. The large deflections of slender wind turbine blade will inevitably
lead to geometric nonlinearities [2], e.g. nonlinear coupling between torsion and deflection, which
complicates the governing equations of motion. To simplify the solution of the nonlinear equations, in the
current research, a novel finite-difference method was proposed to solve the nonlinear equations of static
beam model for… More >

Abstract Short-term wind process is normally assumed to be a Gaussian distribution, such as TurbSim, the widely

non-Gaussian wind filed using translation process theory and spectral representation method. This study
presents a comprehensive investigation on power production and blades fatigue damage of floating offshore
wind turbines (FOWTs) to the non-Gaussian wind field. The comparisons of Gaussian and non-Gaussian

Abstract A multiscale approach [1] that couples the finite-element method (FEM) and the discrete-element method
(DEM) is employed to model and analyse the earthquake fault rupture-soil-foundation interaction (FR-SFI)
problem. In the approach, the soil constitutive responses are obtained from DEM solutions of representative
volume elements (RVEs) embedded at the FEM integration points so as to effectively bypass the
phenomenological hypotheses in conventional FEM simulations. The fault rupture surfaces and shear
localization patterns under normal faults with or without foundation atop have been well captured by the
multiscale approach and verified with available centrifuge experimental [2] and numerical results [3]. By

Abstract Wetting and capillary phenomena on the macroscale are ubiquitous and have been well understood.
However, the relevant physics and mechanics on the nano-scale still remain mysterious. In this talk, I would
like to discuss the exploration of capillarity from a nanoscopic perspective, including wetting, evaporation
and condensation. At the solid/liquid interface, the liquid exhibits a pronounced layered structure that
extends over several intermolecular distances from the solid surface. Our recent studies have shown that
such molecular detail could provide some new understanding on century-old classical theory in this field,
such as Young’s equation [1] and Kelvin equation [2]. More >

Abstract The different elastic properties of tension and compression are obvious in many engineering materials,
especially new materials. Materials with this characteristic, such as graphite, ceramics, and composite
materials, are called bi-modulus materials. Their mechanical properties such as Young’s modulus have
randomness in tension and compression due to different porosity, microstructure, etc. To calibrate the
mechanical properties of bi-modulus materials by bridging FEM simulation results and scarce experimental
data, the paper presents a data-fusion computational method. The FEM simulation is implemented based on
Parametric Variational Principle (PVP), while the experimental result is obtained by Digital Image
Correlation (DIC) technology. To deal… More >

Abstract The family of 2D transition-metal oxides and dichalcogenides with 1H phase (1H-MX2) has sparked great
interest from the perspective of basic physics and applied science. Interestingly, their performances could
be further regulated and improved through strain engineering. Effective regulation is founded on a wellunderstood mechanical performance, however, the large number of 1H-MX2 materials has not yet been
revealed. Here, a general theoretical model is constructed based on the molecular mechanics, which
provides an effective and rapid analytical algorithm for evaluating the mechanical properties of the entire
family of 1H-MX2. The validity of the constructed model is verified by molecular dynamics… More >

Abstract Ion dynamics and precise control in nanochannels play key roles in biological systems, energy conversation,
and environmental engineering. However, the mechanics behaviors of ions and their manipulation
mechanism under extreme confinement remain largely unexplored. Biological ion channels acting as life’s

vital life functions. This biological inspiration motivates the quest for artificial structures with simultaneous
functions of ion selectivity, fast transport and electrical gating at the atomic scale. Here, we experimentally
