摘要
本文建立了光弹性力学的分区相似耦联势能原理及相似耦联有限元法和广义分区相似耦联势能原理及广义相似耦联有限元法．这些分区相似耦联势能原理及相似耦联有限元法的建立，为解决光弹性力学中泊松比对冻结应力法精度的影响奠定了理论基础和提供了从模型体应力场向原型体应力场转换的计算手段。
Sim-Coupled potential energy principle with the region subdivided into subregions and sAn-coupled finite element method, and generalized sun-coupled potential energy principle with the region subdivided into subregions and generalized sim-coupled finite element method in photoelasticity are established in thes paper. Tile establishments of these sim-coupled potential energy principles with the region subdivided into subregions and the sim-coupled finite element method lay the theoretical foundations for solving the influence of Poisson's ratios on the accuraCy of frozen stress method in photoelasticity and provide the calculation means for transforming the stress fields of models into those of prototypes.
