In Chapter 4, the configurational forces are used to investigate the fracture problems of thermoelastic and electroelastic materials.

第四章采用构型力理论分析了热弹性材料与电弹性材料的断裂问题。

First,they are ferromagnetic intermetallic compoundsundergoing a martensitic transformation from a cubic L21/B2 structure to a complexmodaluted structure. Second,the martensitic transformation behavior of the alloys,which depends on composition and heat treatment,is thermoelastic and exhibits atwo-way shape-memory effect.

第二，其马氏体相变是热弹性的，马氏体相变特性受合金的化学成分和热处理工艺等的影响。

Now, plate equations are topic problem, especially, the thermoelastic plate equations in presence of thermal effect have become important to many mathematician.

目前，板方程就是一个非常活跃的课题，其中考虑了热弹效应的热弹性板的研究也受到了高度重视。
