摘要
采用Christensen各向同性热黏弹性本构关系,考虑湿气和温度变化对热流变简单材料折减时间函数的影响,利用Laplace变换法,证明当材料松弛函数具有时空可分离形式,且在给定的温度场和湿气场仅与时间变量有关时,各向同性、非均匀湿热黏弹性拟静态问题的对应原理仍然成立.
The Christensen＇s isotropic thermo-viscoelastic constitutive relation is adopted to consider influence of moisture and thermal changes on the reduced time for simple thermo-rheological materials.The Laplace transform method is used to show that the correspondence principle for isotropic and nonhomogeneous hygro-thermo-viscoelastic quasi-static problems still holds when relaxation functions have separable forms in space and time,and the given temperature and moisture fields are only related to time variable.
