| Abstract: |
| An explicit finite element method considering the effect of coupling mass for dynamic analysis of fluid saturated porous media is developed.In the paper,the formulas of the explicit finite element are deduced,and the computer program is developed.The results show that the differences between the results of the explicit finite element method and the results of the analytical methods are very small and the accuracy is satisfactory.Application showed that the explicit finite element method developed in the paper is a very efficient method for dynamic analysis of fluid saturated porous media.The effects of coupling mass on the dynamic displacements of solid and liquid phase is also analyzed.It revealed that the coupling mass of fluid saturated porous media has some considerable effects on the dynamic displacements of the liquid phase,but no obvious effects on the dynamic displacements of solid phase. |
