| 摘 要： | 将多孔含液固体问题归结为一个内边界受流体压力作用的复连通域边值问题,利用流体体积变化率与流体压力之间的关系建立了流体夹杂区域边界位移与流体压力之间的线性关系,然后采用边界元方法建立了问题的求解方案。该方法的主要特点是通过一次求解可以同时得到所有边界节点的位移和所有流体夹杂区域的压力。采用上述方法对多孔含液固体的等效力学...

| Abstract: | The problem of solid with fluid-filled pores was considered as a multi-connected domain problem,in which uniform unknown pressure was applied on the inner boundaries.Based on the relationship between the pressure and volume change rate of each fluid-filled pore,the linear expression between the displacement and traction on the internal boundary was constructed,with a computing scheme then developed using the boundary element method to solve such kind of problems.The advantage of the developed method is that... |
