塑性应变的问题

qugan

下图当中，我作记号划分塑性应变，弹性应变，弹性应变=屈服应力/弹性模量，然后用总应变-弹性应变得出=塑性应变，

有限元计算是这样思路吗

For finite element method in dealing with plasticity, at each iteration or load step, the only known variable is total strain. What we need to do is to find the elastic strain components and plastic strain components, which is usually handled by radial return method. Then we need to take the integration over the plastic strain increment to get the stresses.
