The paper presents results of numerical fit of axisymmetricFE model utilizing the modified Gurson model into experimentalmeasurements of tensile strain and contraction evolutions ofnotched bars. This model combines plasticity and damage by intro-ducing porosity of a material in order to predict final fracture.
