变温粘弹性蠕变型本构方程

文中给出了变温蠕变曲线的概念，给出了由一组恒温蠕变曲线确定沿某一温度历史的变温蠕变曲线的方法，给出了终态温度等效蠕变曲线的概念，最后给出了粘弹性材料在变温下的蠕变型本构方程的一般形式。文中证明了热流变简单材料理论是本文理论的特例，揭示了热流变简单材料理论数学方法的物理意义。

THE CREEP CONSTITUTIVE LAW UNDER NONCONSTANT TEMPERATURE STATES

This Paper presents the concept of creep curves under nonconstant temperature states,the method of determining creep curve under nonconstant temperature along a temperature history from a group of creep curves under constant temperature stain, the concept of equivalent creep curve on the terminal temperature and, finaly, the general creep constitutive equations of viscoelastic materials under nonconstant temperature states. It is proved that the theory on thermorheological simple material is a spotal case of this theory. This Paper reveals the physical meaning of the mathematical methods in theory on thermorheological simple material.
