On the stability of mixed polygonal finite element formulations in nonlinear analysis
International Journal for Numerical Methods in Engineering, Volume 125, Issue 9, 15 May 2024.Abstract This article discusses the accuracy and stability of the pressure field in nonlinear mixed displacement‐pressure finite element formulations in solid mechanics. We focus on two‐dimensional mixed polygonal finite element formulations with linear displacement and constant pressure approximations in particular.

Civil Engineering Design, Volume 5, Issue 5-6, Page 67-94, January 2024.Abstract In civil engineering, carbon is typically regarded as a modern material to serve as reinforcement in concrete structures. Compared to steel reinforcement, it features two substantial benefits: It is not sensitive to corrosion, and has an enormously increased tensile strength.

Comparative Study of Algorithms for the Conversion From Surface Mesh Models to Volume Mesh Models
Advances in Civil Engineering, Volume 2024, Issue 1, 2024.The study delves into the performance of different algorithms in the process of converting surface mesh models (SMMs) into volume mesh models (VMMs) required for finite element analysis. The experiment compared the Initial mesh, Delaunay, Frontal, and HXT algorithms, analyzing their central processing unit (CPU) runtime, node count, element count, and ...

Analysis of the Electrostatic Field in Ring-type Domain by SBFEM with Schur Decomposition
工程科学与技术, 2013 :Scaled boundary finite element method (SBFEM) was applied to solve the boundary value problems of the electrostatic field in coaxial-cable, i.e., ring-type domain. To avoid the singularity in eigenvalue method, Schur decomposition was employed to update
