Abstract :
In this work, an effective methodology is introduced for simulation of the crack
propagation in linear poroelastic media. The presence of pores and saturated cracks
that can be accompanied by fluid flow makes the use of poroelastic media inevitable.
In this work, involvement of the time parameter in crack propagation is of particular
importance. The order of doing the work is such that first, derives the fundamental
solutions of a poroelastic higher order displacement discontinuity method
(PHODDM). Then will be provided a numerical formulation and implementation for
PHODDM in a code named linear element poroelastic DDM (LEP-DDM). Analytical
solutions use different times to check the correctness and validity of the proposed
solution and the newly developed code. The numerical results show a good agreement
and coordination with the analytical results in time zero and 5000 seconds. The code
is able to pursue crack-propagation in time and space. This topic is introduced and
shown in an example.
