• DEFORMATION IN A FLUID SATURATED POROUS MEDIUM DUE TO RING AND DISC LOADS

Sanjay Garg*

Abstract


The present investigation is concerned with axi-symmetric deformation in fluid saturated incompressible porous medium whose surface suddenly emanates from a point on the surface and expands radially at constant rate due to time harmonic ring and disc loads. The cases of loads shaped like a ring and disc are considered in details. These loads are chosen so that they exert a constant force on the surface as they expand. Hankel transform technique is used to solve the problem. The integral transform has been inverted by using a numerical inversion technique to obtain the components of stresses and pore pressure in physical domain. The trends of variations of these quantities for both types of loads are depicted graphically.


Keywords
