  • A damage–plasticity constitutive model for the description of fracture in plain concrete is presented. Two approaches – the local model comprising the adjustment of the softening modulus and the non-local model based on spatial averaging of history variables – are applied to the analysis of a concrete bar subjected to uniaxial tension and to a three-point bending test. The influence of mesh size and the decomposition into damage and plasticity components are discussed. It is shown that for the… CONTINUE READING
