The rigid-plastic element-free Galerkin method and its applications in metal forming
Author(s): 
Pages: 44-47
Year: Issue:  z1
Journal: JOURNAL OF PLASTICITY ENGINEERING

Keyword:  金属塑性成形无网格方法数值模拟刚塑性;
Abstract: 分析了无网格方法的优点以及其在金属塑性成形过程数值模拟中的应用,结合刚塑性材料条件的假设,介绍了基于刚塑性理论的无网格伽辽金方法,运用不完全广义变分原理,采用罚函数方法引入体积不变条件,给出了其刚度矩阵方程和求解列式.平面应变锻造过程的数值算例表明:无网格Galerkin方法是处理大变形畸变问题的一种有效方法.
