Experimental and Numerical Modeling of the Phenomenon of Delamination Cracking in S235 Steel

Abstract:

In the paper was compared the stress state in front of the crack for SEN(B) specimens of S235RJ steel without and with delamination cracks. Stress distribution and characteristics of stress state triaxiality were calculated for both type of specimens. It was showed a reduction in the stress fields and triaxiality parameters in front of the main crack in the presence of delamination cracking.
