Original abstract

The effect of stress multiaxiality on void nucleation and growth at ductile fracture was studied for a Eurofer97 steel. Tensile testing of smooth and notched round bars was performed. The fractography and metallography analysis on broken halves of tensile bars together with the image analysis were carried out. The increasing stress multiaxiality in the bars lowers the strain at fracture. The ductile damage of the steel consists from the nucleation of the voids by decohesion mechanims, their gradual growth and finishes by rapid void coalescence. The increasing stress multiaxiality causes larger growth of voids together with observed restriction of void nucelation.
