Abstract
This report deals with contact problem of rectangular poroelastic body put between two parallel impermeable rigid planes, subjected to vibrational compression. The problem was analyzed based on two dimensional theory of poroelasticity and load sharing ratio by solid contact and by fluid were obtained from stress components at contact surface. At high excitation frequency, load sharing ratio by fluid becomes large especially at the material center and its phase shift approaches zero, which lead to reduction of load sharing ratio by solid contact and increase of its phase delay. In addition, effects of several parameters to load sharing ratios were examined.
