Abstract EN
We model the fluid flow within the crack as one-dimensional flow and assume that the flow is laminar; the fluid is incompressible and accounts for the time-dependent rate of crack opening.
Here, we discretise the flow equation by finite volume methods.
The extended finite element methods are used for solving solid medium with crack under dynamic loads.
Having constructed the approximation of dynamic extended finite element methods, the derivation of governing equation for dynamic extended finite element methods is presented.
The implicit time algorithm is elaborated for the time descritisation of dominant equation.
In addition, the interaction integral method is given for evaluating stress intensity factors.
Then, the coupling model for modelling hydraulic fracture can be established by the extended finite element methods and the finite volume methods.
We compare our present numerical results with our experimental results for verifying the proposed model.
Finally, we investigate the water pressure distribution along crack surface and the effect of water pressure distribution on the fracture property.
