An overview of the modelling of quasi-brittle as well as ductile damage is given. The multiscale procedure employing the nonlocal continuum theory is described in more detail. The softening is introduced at the microlevel in the microstructural volum

A damage model for quasi-brittle materials embedded into the two dimensional C1 continuity triangular finite element formulation based on the strain gradient continuum theory is considered. The isotropic damage law is applied to the higher-order stre

Two-scale damage model for quasi-brittle heterogeneous materials

Autor: Putar, Filip

In this contribution, an existing two-scale model employing the nonlocal strain gradient theory at both micro- and macrolevel is extended and transformed to the analysis of the softening materials. The discretization of both levels is performed by me
