abstract = "We develop a material force method to calculate the energy release rate and work rate of dissipation for ductile fracture. We obtain expressions for the global material and dissipation forces from a global balance of energy-momentum that incorporates the effects of plastic dissipation. For implementation in a finite element framework, we develop an equivalent domain integral formulation from the weak form of the energy-momentum balance. A Galerkin discretization of the domain integral expressions produces approximations for the global material and dissipation forces that are the weighted sum of corresponding nodal forces. We verify the material force formulation and the numerical method for the model problem of cohesive fracture in a K-field. The model problem is also used to examine the effects of bulk material properties on the work of dissipation.",
