摘要
本文建立了与刚塑性有限元中总能耗率泛函近似的G泛函 ,用其泛函的驻值条件得到的线性方程组解出的速度场作为真实速度场迭代求解中的迭代初始值 ,此初始值与真实值比较接近 ,可减少迭代次数 ,加快收敛。
A function is set up which is similar to energy consumed rate function.It can be used to make non linear equation got from standing value condition and the latter can be converted into linear equation.Through calculation a velocity field can be got,which can act as initial value of calculating real velocity field.This value is close to real one and can decrease times of iteration.
