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.
