abaqus 弹塑性本构的编程与实现，无限元模型的建立与实现，算例(The programming and implementation of ABAQUS elastoplastic constitutive model, the establishment and implementation of infinite element model, an example)

ABAQUS是一款可以自定义材料属性的软件，本文档介绍了怎么在子程序中实现弹塑性本构。(ABAQUS is a kind of software that can customize material properties. This document describes how to realize elastic-plastic constitutive in subroutines.)

ABAQUS 用户子程序 UMAT 的开发方法，采用 FORTRAN 语言编制了各向同性硬化材料模型的接口程序，研究该类材料的弹塑性本构关系极其实现方法(Based on the development method of user subroutine UMAT of ABAQUS, the interface program of isotropic hardening material model is compiled by F
