eng Abstract:
Exact measurement of deformation and fracture material characteristics in laboratory enables determination of micromechanical parameters for GTN model. The attention is paid on the influence of initial value of J- integral and the slope of R-curve on the local stress triaxiality. Good agreement between numerical simulation and experimentally measured R-curve was found.
