Abaqus implementation of monolithic and staggered schemes for quasi-static and dynamic fracture phase-field model

The phase-field model for fractures regularizes crack diffusion using a length-scale parameter. The displacement fields and the phase-field in a coupled system can be solved as either fully coupled “monolithic” or sequentially coupled “staggered” fields. In this paper, we employ the commercial finite-element software Abaqus to solve the monolithic and staggered phase-field models using a user-defined element (UEL) and user-defined material...
