Splits (decompositions) of the mechanical energy potential for regularised fracture models, like phase-field fracture andeigenfracture, are frequently motivated by the statement that crack nucleation and crack growth have to be prevented at compressionloads. The intention of the talk is to show that this energy decomposition is an essential part of such fracture models, and toinvestigate the underlying mathematical statement and its physical interpretation.

In this work, a phase-field formulation is proposed to describe ductile fracture in fiber-reinforced concrete materials. By incorporating an elastoplastic bulk material formulation into the promising Representative Crack Element(RCE) framework, physically meaningful kinematic behaviors at the crack surface could be observed when facing crack opening, closing and shear loading scenarios.
