Mesh sensitivity analysis of the solution to hydraulic fracture problems based on a smeared crack model

Mesh quality is an important factor that affects the simulation results in nonlinear soil/rock mechanic problems. The effect of aspect ratio of element (AR) on calculation was analyzed in numerical solution of hydraulic fracture for the smeared crack model. Elasticity was measured by adopting the porous elastic (PE) and linear elastic (LE) constitutive models. Regarding to material yielding and failure, both the Drucker-Prager (DP) and …
