Abstract:Variationally consistent phase-field methods allow for an efficient investigation of complex three-dimensional fracture problems (see [1,2]). However, formulations for large deformation problems often exhibit a lack of numerical stability for different loading scenarios. In the underlying contribution a novel formulation for finite strain polyconvex elasticity is adapted to phase-field fracture problems. In particular we introduce a new anisotropic split based on the principal invariants of the right Cauchy-Gr… Show more
