中文摘要:

这篇论文处理我击碎的模式在用精细的数字 moir é技术的飞机压力状况下面的一张击碎的橡胶表的问题。通过四步自动化穗分析的转移阶段的方法,在笛卡儿的坐标系统的排水量地被给。由并列变换的方程,在极的坐标系统的光线、圆形的排水量分布被获得。裂缝尖端附近的排水量 isoline 分布和排水量向量分布被讨论。裂缝尖端附近的紧张 isoline 分布也在这篇论文被分析。最后,分发近为机械地裁定裂缝尖端与部门部门方法被讨论。

英文摘要:

Based on the thermodynamics of irreversible processes, the mass conservation equation and heat energy balance equation are established. The governing equations of thermal consolidation for homogeneous isotropic materials are presented, accounting for the coupling effects of the temperature, stress and displacement fields. The case of a saturated medium with a long cylindrical cavity subjected to a variable thermal loading and a variable hydrostatic pressure (or a variable radial water flux) with time is considered. The analytical solutions are derived in the Laplace transform space. Then, the time domain solutions are obtained by a numerical inversion scheme. The results of a typical example indicate that thermodynamically coupled effects have considerable influences on thermal responses.
