Experimental and numerical determination of the parameters of the Gurson model for ductile fracture
Original language description
The paper presents results of numerical fit of axisymmetric FE model utilizing the modified Gurson model into experimental measurements of tensile strain and contraction evolutions of notched bars. This model combines plasticity and damage by introducingporosity of a material in order to predict final fracture. Although some of the parameters of the model can be determined by microscopic investigation of a specimen, the majority of the parameters need to be determined by fitting numerically obtained results into experimental ones. In this paper, it is shown that such a fit is achevable. However, the uniqueness of the obtained parameters is questionable.
