Immersed traction boundary conditions in phase field fracture modelling

Abstract

Phase field approaches are an increasingly popular method for modelling complex fracture problems and have been applied to a number of real-world settings. In some applications, pressure forces, or more generally traction terms, must be considered on the crack faces. However, application of appropriate boundary conditions to represent these tractions is non-trivial, since phase field models do not include a direct description of the fracture surface due to their diffuse nature. This paper summarises one- and two-domain approaches to including immersed traction boundary conditions and states the authors’ intention to implement and evaluate these methods in an hp-adaptive discontinuous Galerkin finite element framework.
