Experimental determination of the void volume fraction for S235JR steel at failure in the range of high stress triaxialities
This paper is concerned with the critical void volume fraction fF representing the size of microdefects in a material at the time of failure. The parameter is one of the constants of the Gurson-Tvergaard-Needleman (GTN) material model that need to be determined while modelling material failure proce...
