Cohesive crack for quasi-brittle fracture and numerical simulation of hydraulic fracture
This chapter introduces the concepts and the numerical processes of modeling hydraulic fractures using the 3-dimensional finite element method (3D FEM). The subsequent sections include the following:
• Cohesive crack model concepts. • Popular cohesive crack models. • Cohesive element with pore pressure designed for the simulation of hydraulic fractures. • Example numerical analysis of the hydraulic fracture of a reservoir formation performed
with the Abaqus 3D FEM program.
