... of Shaximiao Bottom, Ziliujing. and Xujiahe. A series of tests are conducted to investigate the evolution of rock mechanical properties subjected to the joint action of temperature and in-situ stress based on a self-developed experimental setup. The results indicate that the rock strength under in-situ...

... fracture evolution hydrogen technical conference literature Abstract Rock salt is a very complex material. Simulation of the non-linear and time-dependent mechanical behavior of salt caverns requires advanced constitutive models, relevant sets of parameters and accurate numerical computations...

... analyses of the dissipative process are provided through the shear stress field and the evolution of the shear stress, displacement, and energy balance. We obtain through the present model the total of dissipated energy thanks to the energy balance. Also, while the elastic energy variation can be positive...

... of deformation and stress (Bazant, 1991; Bazant & Jirasek, 2002). However, the introduction of damage locally at a material point leads to mesh-dependent energy dissipation and non-uniqueness of solution. Therefore, regularization methods have been proposed to regularize damage evolution to be a non-local...

... ABSTRACT: Hydrocarbon production from fractured reservoirs requires accurate mapping of the fracture network and their conductivities. Fracture networks develop during evolution of sediments mostly by tectonic and gravitational forces. Evolution of fractures was estimated by the geomechanical...

We assume that the group of induced fractures (when subjected to the confining stress and pore...

... in the Upper Cretaceous/Lower Tertiary (Mohr et al., 2005). Enormous amounts of geological information can be exploited and well-analyzed using the 3D seismic technique. In detail, the architecture and evolution of the fault system are determined quantitatively and qualitatively by utilizing 3D seismic...
