摘要
文献介绍了弹粘塑性有限无解的数值方法,给出了Mises屈服准则的H矩陈表达式。本文对工程中常用的四种屈服准则,即Mises,Tresca,Mohr-coulomb,Drucker-Prager准则,给出了H矩阵的统一格式,提供厂消除Tresca,Mohr-Coulomb准则奇异性的方法并给出了公式。
Reference [1] intruduced numerical method of elasto-viscoplastic finite element solution and presented expression of matrix Hfor the Mises criterion. In this paper, the author derives the unified formula of matrix Hfor the four yield criteria, i.e., Mises, Tresca, Mohr-Coulomb and Drucker-Prager which are often appeared in engineering, discusses method of eliminating singularity in Tresca or Mohr-Coulomb criterion, and obtains corresponing formula.
