Embedded band xfem
WebThe extended finite element method (XFEM) is used to solve the elastic deformation of rock, and the mixed boundary element method (MBEM) is adopted to accurately calculate the unsteady flux between matrix and fracture. WebJun 1, 2013 · The BEM solution for an elastodynamics problem generally requires the utilization of the Green’s function of a homogeneous medium of infinite extent—i.e., the analytical solution of the displacement field of the wave response induced by a point load within the infinite medium.
