摘要
依据变温下一般热粘弹性材料的蠕变型本构方程,通过对记忆积分的化简,推导出变温粘弹性有限元方法的一般列式。它适用于各种热粘弹性材料在变温下的有限元计算。
According to the creep constitutive law of thermoviscoelasticity under nonconstant temperature state its formulas of finite element method are derived by simplifying the hereditary integral.These formulas can be applied to finite element calculation of the kinds thermoviscoelastic materials.
