Dynamic analysis of fluid-saturated porous media by using explicit finite element method

An explicit finite element method for dynamic analysis of fluid-saturated porous media is developed. The formulae for the explicit finite element method are given. By using this method, computation effort and memory space can be reduced considerably. The present method is compared with analytical methods, and the degree of accuracy is satisfactory. It is shown that the method developed in this paper is a very effective method for dynamic analysis of fluid-saturated porous media.
