Non-linear constitutive model for mortar

Jiri Brozovsky jr., Ivan Kolos, Alois Materna

Abstract


The non-linear constitutive model of a mortar is presented in the paper. The model is based on the equivalent one-dimensional stress-strain relation and on the smeared crack model. The limits of the one-dimensional relation are computed from the 2D state of stress with the help of the Kupfer failure condition. The smeared crack model is used for the modeling of tension crack propagation and the elasto-plastic behavior is assumed for the compression. It is assumed that concrete ca include up to two perpendicular crack direction. This model is similar to the ones that are used for a non-linear modeling of concrete.
