近年来,塑性力学的工程应用正在迅速扩大.借助于计算机和新的数学工具,弹塑性分析、极限分析和安定分析已扩展到复杂结构问题。板料成形中的回弹、皱曲和拉伸失稳的研究有很大进展.在结构的塑性动力响应问题中,更多地注意到弹性效应、几何变形效应以及特异现象.结构的耐撞性和碰撞能量吸收装置也是一个迅速发展的新领域.人们越来越主动地利用塑性变形为特定的目的服务. In recent years, engineering applications of plastic mechanics are rapidly expanding. With the aid of computers and new mathematical tools, elastoplastic analysis, limit analysis, and stability analysis have been extended to complex structural problems. The research on springback, wrinkling, and tensile instability in sheet metal forming has made great progress. In the issue of plastic dynamic response of structures, more attention has been paid to elastic effects, geometric deformation effects, and specific phenomena. Sex and collision energy absorption devices are also a rapidly developing new field. People are increasingly using plastic deformation to serve specific purposes.
