摘要
以Biot理论为基础，将弹性应变与非弹性应变均取作状态变量，引入耗散势，建立广一种率相关非弹性本构关系及演变方程，进而导出一种广义的粘弹性本构方程．
In this paper, the elastic strain and inelastic strain are both chosen as state variables. On the basis of Biot theory and by introducing a dissipation potential, a rate-dependent evolution equation is derived. A generalized viscoelastic constitutive equation is then obtained.
