摘要
本文在设定运动许可的速度场基础上，求出应变分布，推导出球应力分量的计算方法，从而解决了上界法中应力分布的求解问题，并对圆柱体镦粗过程进行了求解。
On the basis of establishing movement permiting field of velovity. the strain distribution and the equation of sphere stress tensor are griven. The problem of solution on stress distribution is solved in upper-bound analysis. And then the solution of upsetting cylinder is given.
