理想塑性轴对称问题的一般方程
On the General Equations of Axisymmetric Problems of Ideal Plasticity
-
摘要: 本文引用速度势函数,将理想塑性轴对称问题化为二个非线性的偏微分方程,根据导得的方程讨论了Haar-Kármán假设对于Mises屈服准则及与其相关联的流动法则的协调性问题。Abstract: In this paper, introducing a velocity potential, we reduce the fundamental equations of axisymmetric problems of ideal plasticity to two nonlinear partical differential equations. Front these equations we discuss compatibility of Harr-Kármán hypothesis with von Mises yield criterion and the associated flow law.
