... of bitumen (matrix) and grains (inclusions). Firstly, the elastic properties of bitumen are expressed as functions of both temperature and time. Similarly, the Eshelby's, Mori-Tanaka's and differential methods are used to write the elastic properties of oil sand (composite material) as functions of both...

... are able to model 3D fracture propagation. We use analytical Eshelby's solution that evaluates near-tip stress of an ellipsoidal fracture to validate the BEM results. approach. The numerical method used to compute the stress field in the vicinity of a fracture is 3D BEM, [13] and [14], based on angular...
