爆轰荷载作用下球空腔热流固耦合动力响应

基于饱和多孔弹性介质热流固耦合动力模型(THMD)及控制方程，研究了爆轰荷载作用下球空腔内壁面受到随时间变化热、力冲击作用下的热流固耦合动力响应。利用Laplace变换技术，对控制方程进行解耦，获得了温度、位移、孔隙水压力和应力积分形式解。采用Laplace逆变换得到数值结果，分析了热流固耦合参数的影响特性，并将热流固耦合结果与热弹性条件下的结果进行比较，以验证热流固耦合条件下结果的正确性。

Thermo-hydro-elastodynamic response of spherical hollow chamber under explosive loading

Based on a model of coupling thermo-hydro-mechanical dynamic response for a saturated poroelastic medium presented by the authors, the dynamic response of a spherical hollow chamber when subjected to a time dependent thermal/mechanical shock on the inner surface is investigated. By using Laplace transform method, the governing equation is decoupled; and the integral solutions of temperature, displacement, pore pressure and stress are derived. The numerical results are obtained by using the inverse Laplace transform method; and the results are used to analyze the influences of the coupling parameters of thermo-hydro-mechanical dynamic response. At last, the solutions are compared with those of the thermoelastic medium; and the validity of the results of the thermo-hydro-mechanical dynamic response with a spherical hollow chamber in the saturated poroelastic medium is ascertained.
