Characterization of slip lines in single edge notched tension specimens

Abstract

The application of slip line analysis in weld failure assessment has not gained much attention to date. The presented research aims to predict slip line patterns taking into account the complex heterogeneous structure of the weld. A preliminary study based on Single Edge Notched Tension (SENT) test results sampling pure base material, i.e. not containing any welds is conducted to assess the impact of side grooves on slip line behaviour and to validate slip line theory and finite element analysis.
