Here is our paper of the NAFEMS world congress 2021 with the title “Efficient stress linearization in FEA continuum models for weld fatigue assessment” concerning the sections, a new feature of LIMIT®. Sections were developed in order to analyze weld throats in models meshed with solids. Based on nodal forces and an unique linearization scheme LIMIT® calculates structural stresses in the throat of fillet welds. This way the assessment of root points in fillet and lap welds is possible without the necessity of effective notch modeling.
