摘要

在结构安定分析的框架内，提出了一种将多边形有限元法与二次优化技术相结合的创新数值方法。所得到的优化问题被表述为二阶锥规划(SOCP)问题，并使用MOSEK原对偶内点求解器有效地求解。数值实验验证了该方法的计算效率和有效性。

A polygonal finite element method for shakedown analysis of structures

This study presents an innovative numerical method that combines the polygonal finite element method (Poly-FEM) with conic optimization techniques within the framework of structural shakedown analysis. The resulting optimization problem is formulated as a second-order cone programming (SOCP) problem and is efficiently solved using the MOSEK primal-dual interior-point solver. Numerical experiments validate the computational efficiency and efficacy of the proposed approach.
