摘要
本文提出了光弹理论的耦联有限元法,对于耦联系统,如已知其一系统(模型体)的离散解,可据耦联有限元法求出其另一相应系统(原型体)的对偶离散解,数值计算表明,应用此法所求得对偶解的精度是相当高的。这是一个创新的方法,它具有极重要的理论意义和实际意义。
In this paper, the coupled finite element method ofphotoelasticity is presented. This method is that for a pair ofcoupled systems, if the dispersed solution of one of some systems(model body) is given, the dispersed dual solution of othercorresponding system(prototype body) can be solved by means ofthe coupled finite element method. The calculated values showthat the accuracy of dual solutions found in coupled finiteelement method is high. The coupled finite element method is anew method and has important significance in the theory and
