摘要
本文主要解决的问题有两点：１、在应力空间和应变空间中表示应变能密度函数的方法；２、利用正交变换，将应变能密度函数用模态应力和模态应变表示的方法．本文的结果，可以更深刻地揭示应变能密度函数的本质。
In this paper, we have discussed two problems:(1) the method of representation of strain energy density function in the stress and strain spaces;(2) by means of orthogonal transformation, the strain energy density function can be represented by model stresses and strains. The results reveal profoundly innate characteristics of the strain energy density function and provide a new concept and method used in research on material propertities.
