A convergent adaptive finite element method for a phase-field model of dynamic fracture

Ram Manohar, S. M. Mallikarjuaniah

We propose and analyze an adaptive finite element method for a phase-field model of dynamic brittle fracture. The model couples a second-order hyperbolic equation for elastodynamic…

An -adaptive discontinuous Galerkin discretization of a static anti-plane shear crack model

Ram Manohar, S. M. Mallikarjunaiah

We propose an -adaptive discontinuous Galerkin finite element method (DGFEM) to approximate the solution of a static crack boundary value problem. The mathematical model descri…
