A non-local elasto-plastic model to simulate localizations of deformations in quasi-brittle materials

The paper presents results of FE-calculations of the behaviour of quasi-brittle materials during a biaxial compression test. An clasto-plastic material model with a linear Drucker-Prager criterion using isotropic hardening and softening and non-associated flow rule was used. A non-local approach was applied to capture realistically localization of deformations. A characteristic length was incorporated via a weighting function.
