Modeling of damage phenomena using higher-order finite element formulation
It is well-known that damage phenomena cannot be objectively modeled by using the classical continuum theory because the differential equations which describe the deformation process may lose the elliptic characteristic once the damage is initiated. Mathematical description of the model in that case becomes ill-posed and numerical solutions do not converge to a physically meaningful solution. To overcome these problems, most of the regularization techniques developed are based on the improvement of the classical continuum model by its enrichment with the internal length scale parameters in various forms. Among these techniques especially nonlocal theories are known, which have been shown to be the most versatile. One of them is the strain gradient continuum theory, which introduces the nonlocality in the model through additional gradient term in the strain energy density function.
