Plastic Model with Non-Local Damage Applied to Concrete

Popis výsledku v původním jazyce

The present paper deals with a certain class of regularized models for concrete failure, combining plasticity with nonlocal damage. The plastic part is local and uses a yield condition formulated in the effective stress space. Softening is incorporated through the damage part of the model. Damage is considered as isotropic and linked to the evolution of plastic strain. The regularized version of the model is based on weighted spatial averaging of the damage-driving variable. Conditions for a mesh-independent description of the localized zone of inelastic strains are studied using one- and two-dimensional examples solved by simple nonlocal damage-plasticity models, in two dimensions with nonassociated flow. Then, the framework is applied to an advancedmodel for concrete. Structural examples of tensile and compressive failure are presented.
