【摘要】 关于粘弹性材料的解析解不多，而关于变温粘弹性材料的解析解则更少．本文在三维变温粘弹性本构方程［1］的基础上，将构件材料的终态温度等效松弛曲线表示成负幂指数的形式，推导出了粘弹性材料的杆在轴力作用下处于变温状态下的位移的解析解．更多还原

【Abstract】 There are not many analytical solutions for the viscoelastic material, and still less analytical solution for the viscoelastic material under nonconstant temperature state. In this paper, based on the 3-D constitutive equation [1] of thermoviscoelasticity under nonconstant temperature state, the equivalent relaxation curve of the material at terminal temperature state is expressed as the negative exponential function, and the analytic solution of the displacement is developed for the rod made of the viscoelastic material under the action of the axial force and nonconstant temperature state.更多还原
