STRESS ANALYSIS AROUND A FRACTURE USING POROELASTIC INDIRECT BOUNDARY ELEMENT METHOD

the necessity of having knowledge about stress, pressure and fracture dimensions for hydraulic fracture applications was caused many researchers to concern about developing efficientnumerical methods for fracture problems. The discontinuities in this kind of problems made the analysis more complex than routine numerical analysis. In this paper we presented an indirect boundary element method called Displacement Discontinuity method. The DD like other boundary element methods reduce problem dimensions by one. Our code is based on DDM for 2D poroelastic fracture analysis. It can calculate stress and pressure distribution around the fracture
