| 摘 要： | 本文讨论了理想弹塑性材料在动载荷下的塑性位移的限界问题，给出了塑性位移的上界估计式。同时又把结果推广到线性强化材料的情形。此外，本文还以一个简单弹簧－质量系统为例对结果进行了校核。

| Abstract: | This paper deals with the appropriate measures of bounding on plastic displacements of elastic-perfectly plastic structures subjected to dynamic loadings. The upper bounds for plastic displacement are given in the form of inequalities. The results achieved are extended to elastic work-hardening of materials under the assumption of a piecewise linear yield surface. As an example of its practical applications the results are checked with the case of a simple spring-mass system. |
