Abstract Scope |
By introducing a diffuse crack representation that depends on the critical energy release rate and an intrinsic length scale, phase-field modeling of fracture provides the framework for the formulation of physically-based gradient damage models that can be efficiently implemented in finite element calculations. Here, a phase-field formulation is coupled with plasticity at large strains to model ductile fracture in metals and implemented using the open-source FEniCS finite element computing platform, which is referred to as Fenics-Forming. Numerical simulations of localized necking in tensile testing are described to demonstrate the ability of Fenics-Forming to predict complex plastic strain localization and crack paths. The role of Fenics-Forming as a digital object of a digital twin of forming processes is discussed. |
