Original Abstract

The contribution deals with the simulation of R-curve using completed Gruson model of ductile fracture. The R-curve was experimentally determined for a Eurofer97 steel in previous study. The simulations of the tests were carried out by FEM software ABAQUS 6.11 in Standard and Explicit modules. The Gurson parameters were identified by single specimen method of smooth tensile test specimen and from metallographic examination of fracture micro-mechanism. The identification was supported by parametric studies. Comparing experimental and simulated R-curve the ductile tearing was not successfully achieved. Insufficient calibrated parameters as a result non-uniqueness problem of single specimen method were found.
