Coupled peridynamic modeling of fluid-driven fractures in solids
Fluid-driven fracturing in solids is involved in many industrial operations and natural processes, such as hydraulic fracking in the petroleum industry, carbon sequestration, and geothermal systems. The intricate interplays between crack growth, fluid flow, and solid deformation pose grand challenges in the numerical modeling of such processes. The particle-based peridynamics theory, serving as a non-local reformulation of classical continuum mechanics, has been developed for modeling the fracturing of solids. In this presentation, Dr. Zhu will share recent research efforts on the development of a coupled total- and semi-Lagrangian peridynamics method for modeling fluid-driven fracturing problems with reference to various engineering applications.
