该成果是上海交通大学工程力学系承接上海市科学技术基金项目“塑性极限平衡理论与应用研究”的内容。科技人员对随动强化材料的安定理论进行了研究,提出了“在进行安定分析时,所选择的残余应力场与塑性应变场是可以不相关”这一新的认识。并对半球封头圆柱壳这类复杂结构求出了安定
The result is that Shanghai Jiaotong University Department of Engineering Mechanics to undertake the Shanghai Science and Technology Fund Project “plastic limit equilibrium theory and application of” content. Scientists and technicians have studied the stability theory of the follow-up strengthening material and proposed a new understanding that “the residual stress field and the plastic strain field should be irrelevant during the stability analysis”. And to the hemisphere head cylindrical shell such complex structure obtained stability
