Summary

With the developments of science and engineering techniques, numerical simulation and data analysis play more and more important roles. Numerical simulations in science, engineering and society fields have developed rapidly in the recent decades. In recent years, the study of data analysis has been paid more attention because of the development of big data. And the numerical methods in artificial intelligence are also important.


Numerical simulation for various problems in science and engineering fields is based on the numerical methods, such as finite element method, boundary element method and meshless method. Various numerical methods are presented for solving the problems in different fields, and the corresponding computational efficiency, accuracy and convergence are studied as well. With the development of big data, numerical simulation combined data analysis has become more important for the problems in science, engineering and society fields. And the numerical methods in artificial intelligence should be investigated too. The numerical methods in science and engineering should be combined with the ones in big data and artificial intelligence to solve various complicated problems in engineering fields.


We particularly take an interest in manuscripts that report relevance of numerical methods in engineering analysis, data analysis and artificial intelligence. The special issue will become an international forum for researchers to summarize the most recent developments of the numerical methods in engineering analysis, data analysis and artificial intelligence within the last five years, especially for new methods and new problems. Moreover, the manuscripts on the theories of numerical methods and data analysis for complicated science, engineering or social problems are welcome. We also concern the development of the corresponding numerical methods on big data and artificial intelligence. Potential topics include, but are not limited to:

•      New theories of numerical methods

•      New methods for engineering analysis, data analysis and artificial intelligence

•      Numerical simulation and data analysis for complicated engineering problems

•      Data system and analysis in society fields

•      Software or programming of numerical methods

•      Future strategies of numerical methods

  • An Intelligent Optimization Method of Reinforcing Bar Cutting for Construction Site
  • Abstract To meet the requirements of specifications, intelligent optimization of steel bar blanking can improve resource utilization and promote the intelligent development of sustainable construction. As one of the most important building materials in construction engineering, reinforcing bars (rebar) account for more than 30% of the cost in civil engineering. A significant amount of cutting waste is generated during the construction phase. Excessive cutting waste increases construction costs and generates a considerable amount of COCO2 emission. This study aimed to develop an optimization algorithm for steel bar blanking that can be used in the intelligent optimization of steel bar engineering to… More

  • Improved Staggered Algorithm for Phase-Field Brittle Fracture with the Local Arc-Length Method
  • Abstract The local arc-length method is employed to control the incremental loading procedure for phase-field brittle fracture modeling. An improved staggered algorithm with energy and damage iterative tolerance convergence criteria is developed based on the residuals of displacement and phase-field. The improved staggered solution scheme is implemented in the commercial software ABAQUS with user-defined element subroutines. The layered system of finite elements is utilized to solve the coupled elastic displacement and phase-field fracture problem. A one-element benchmark test compared with the analytical solution was conducted to validate the feasibility and accuracy of the developed method. Our study shows that the result… More

  • A Parallel Computing Schema Based on IGA
  • Abstract In this paper, a new computation scheme based on parallelization is proposed for Isogeometric analysis. The parallel computing is introduced to the whole progress of Isogeometric analysis. Firstly, with the help of the “tensorproduct” and “iso-parametric” feature, all the Gaussian integral points in particular element can be mapped to a global matrix using a transformation matrix that varies from element. Then the derivatives of Gauss integral points are computed in parallel, the results of which can be stored in a global matrix. And a middle layer is constructed to assemble the final stiffness matrices in parallel. The numerical example results… More

  • The Improved Element-Free Galerkin Method for Anisotropic Steady-State Heat Conduction Problems
  • Abstract In this paper, we considered the improved element-free Galerkin (IEFG) method for solving 2D anisotropic steady-state heat conduction problems. The improved moving least-squares (IMLS) approximation is used to establish the trial function, and the penalty method is applied to enforce the boundary conditions, thus the final discretized equations of the IEFG method for anisotropic steady-state heat conduction problems can be obtained by combining with the corresponding Galerkin weak form. The influences of node distribution, weight functions, scale parameters and penalty factors on the computational accuracy of the IEFG method are analyzed respectively, and these numerical solutions show that less computational… More

  • Pollution Dispersion in Urban Street Canyons with Green Belts
  • Abstract In this study, numerical simulations were used to explore the effects of roadside green belt, urban street spatial layout, and wind speed on vehicle exhaust emission diffusion in street canyon. The diffusion of different sized particles in the street canyon and the influence of wind speed were investigated. The individual daily average pollutant intake was used to evaluate the exposure level in a street canyon microenvironment. The central and leeward green belts of the road were the most conducive to the diffusion of pollutants, while the positioning of the green belts both sides of a road was least conducive to… More

  • Mechanical Properties of Soil-Rock Mixture Filling in Fault Zone Based on Mesostructure
  • Abstract Soil-rock mixture (SRM) filling in fault zone is an inhomogeneous geomaterial, which is composed of soil and rock block. It controls the deformation and stability of the abutment and dam foundation, and threatens the long-term safety of high arch dams. To study the macroscopic and mesoscopic mechanical properties of SRM, the development of a viable mesoscopic numerical simulation method with a mesoscopic model generation technology, and a reasonable parametric model is crucially desired to overcome the limitations of experimental conditions, specimen dimensions, and experiment fund. To this end, this study presents a mesoscopic numerical method for simulating the mechanical behavior… More

  • A Fast Element-Free Galerkin Method for 3D Elasticity Problems
  • Abstract In this paper, a fast element-free Galerkin (FEFG) method for three-dimensional (3D) elasticity problems is established. The FEFG method is a combination of the improved element-free Galerkin (IEFG) method and the dimension splitting method (DSM). By using the DSM, a 3D problem is converted to a series of 2D ones, and the IEFG method with a weighted orthogonal function as the basis function and the cubic spline function as the weight function is applied to simulate these 2D problems. The essential boundary conditions are treated by the penalty method. The splitting direction uses the finite difference method (FDM), which can… More

  • Two-Machine Hybrid Flow-Shop Problems in Shared Manufacturing
  • Abstract In the “shared manufacturing” environment, based on fairness, shared manufacturing platforms often require manufacturing service enterprises to arrange production according to the principle of “order first, finish first” which leads to a series of scheduling problems with fixed processing sequences. In this paper, two two-machine hybrid flow-shop problems with fixed processing sequences are studied. Each job has two tasks. The first task is flexible, which can be processed on either of the two machines, and the second task must be processed on the second machine after the first task is completed. We consider two objective functions: to minimize the makespan… More
