多维情形铅块有限变形压缩试验和分析

The finite deformation compress experiment and study of lead under three dimension condition

对铅块的有限变形单向和多向压缩进行了试验研究，在此基础上给出了单向压缩时欧拉描述下的本构方 程，并研究了本构模型用于多维压缩时理论分析的可行性。

In this paper, the finite deformation property of lead under single dimension and three dimension condition are studied, the single dimension Eulor configuration constitutional equation is presented on this basis. It is shown that the constitutional model is feasible under three dimension condition.
