This paper discusses axially symmetric contact problems of rigid punch and poroelastic foundation interaction employing Cowin-Nunziato linear poroelasticity model. It is assumed that the punch base has a flat or parabolic shape, and the contact friction is neglected. Using Hankel's integral transform the considered contact problem is reduced to a solution of a singular integral equation with unknown contact stress. To solve this integral equation, the collocation technique is used. In the case of parabolic...
