塑性力学问题的一种近似算法

APPROXIMATE METHOD OF PLASTICITY THEORY

以e-p曲线为基础的塑性力学新方法与经典方法相比具有不少优点,但毕竟只有少数问题能求得解析解,大量的问题还是得依靠数值方法。探讨了以新方法为基础的塑性力学问题近似数值算法,实例表明,这一近似算法有较好的实用性。

The new method of plasticity based on e-p curve is of obvious advantages over the classical theory method. However, the analytic solutions can be obtained for only a limited number of problems, and a large number of problems have to rely on numerical method to obtain their solutions. An approximate numerical method of the new method is studied in this paper. Example shows that the approximate method is of a good future.
