Analysis of the Void Volume Fraction for S235JR Steel at Failure for Low Initial Stress Triaxiality

Autor: Kossakowski P. G.

Publikováno v: Archives of Civil Engineering, Vol 64, Iss 1, Pp 101-115 (2018)

This paper deals with problems of failure mechanisms of S235JR structural steel. One of the fundamental parameters of the Gurson-Tvergaard-Needleman damage mechanics-based material model is considered in order to describe the behaviour of the materia

Experimental determination of the void volume fraction for S235JR steel at failure in the range of high stress triaxialities

Autor: Kossakowski P. G.

Publikováno v: Archives of Metallurgy and Materials, Vol 62, Iss 1, Pp 167-172 (2017)

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
