Micro Abstract:
In this work an elastic isotropic damage model considering crack-closure and irreversible strains is discussed. After having introduced the model equations of the local model, results of a simple uniaxial strain controlled test on Gauss-point level are presented. Subsequently, the gradient extension of the model (micromorphic approach) is summarized briefly. Finally, the model's properties and robustness are demonstrated by means of a finite element computation of a single edge-notched plate under shear loading, where an adaptive mesh refinement is utilized.
