An elliptical disc anchor in a damage-susceptible poroelastic medium

A flat rigid elliptical anchorage located in a damage-susceptible fluid-saturated poroelastic medium is subjected to an in-plane load, which induces a pure translation in the plane of the anchor. This paper develops computational estimates for the time-dependent displacement of the disc anchor for the classical problem that involves Biot consolidation and compares the results with situations where the porous skeleton can experience micro-mechanical damage that leads to an alteration in both its elasticity and fluid transport characteristics
