Summary
In the last decades, composite materials are increasingly
applied in many branches of industries, due to their higher values of strength
and stiffness, superior thermal properties, and reduced weights, which can
affect the mechanical performances of beam, plate, or shell structural
applications. On the other hand, the discovery of carbon nanotubes (CNTs) or
further nano-scale derivatives of carbon, such as graphene, with their oxide,
opens a new horizon in the material science, and makes these advanced
nano-scale materials an efficient alternative to conventional micro-size
reinforcements such as carbon and glass fibers. The use of carbon-based nanofillers as reinforcement phase in polymers
enables enhanced properties within nanocomposites, namely, high stiffness,
strength, toughness, hardness, heat distortion temperature, and electrical
properties in addition to a reduced processing cost due to their exclusive
nanostructures. In a context where an increased computational demand is
required to solve even more complicated problems, this special issue discusses
about high-performance computational strategies and advanced theoretical
formulations to solve heat transfer problems; thermal and mechanical stresses
(including boundary layer and edge stresses); free vibrations and damping;
transient dynamics; bifurcation buckling, local buckling, face-sheet wrinkling
and core crimping; large deflection and postbuckling problems; effects of
discontinuities (eg, cutouts and stiffeners), and geometric changes (eg,
tapered thickness); damage and failure of sandwich structures; optimization and
design studies.

Three Dimensional Coupling between Elastic and Thermal Fields in the Static Analysis of Multilayered Composite Shells
Salvatore Brischetto, Roberto Torre, Domenico Cesare

Abstract This new work aims to develop a full coupled thermomechanical method including both the temperature profile
and displacements as primary unknowns of the model. This generic full coupled 3D exact shell model permits the
thermal stress investigation of laminated isotropic, composite and sandwich structures. Cylindrical and spherical
panels, cylinders and plates are analyzed in orthogonal mixed curved reference coordinates. The 3D equilibrium
relations and the 3D Fourier heat conduction equation for spherical shells are coupled and they trivially can be
simplified in those for plates and cylindrical panels. The exponential matrix methodology is used to find the
solutions of a…

Static Analysis of Anisotropic Doubly-Curved Shell Subjected to Concentrated Loads Employing Higher Order Layer-Wise Theories
Francesco Tornabene, Matteo Viscoti, Rossana Dimitri
Computer Modeling in Engineering & Sciences, Vol.134, No.2, pp. 1393-1468, 2023, DOI:10.32604/cmes.2022.022237

Abstract In the present manuscript, a Layer-Wise (LW) generalized model is proposed for the linear static analysis of doublycurved shells constrained with general boundary conditions under the influence of concentrated and surface loads.
The unknown field variable is modelled employing polynomials of various orders, each of them defined within
each layer of the structure. As a particular case of the LW model, an Equivalent Single Layer (ESL) formulation is
derived too. Different approaches are outlined for the assessment of external forces, as well as for non-conventional
constraints. The doubly-curved shell is composed by superimposed generally anisotropic laminae, each of them
characterized…
