摘要: 本文从分子运动学理论出发建立了表征材料粘弹性变形的内变量演变方程,从不可逆过程热力学的基本方程和该内变量演变方程导出了积分型线性粘弹性应力应变关系。Abstract: An evolution equation of internal variables which are related to viscoelastic deformation is derived from the theory of molecular motion. Based on this equation and irreversible thermodynamics, a linear viscoelastic constitutive law is found.
