Our NWC21 presentation on the new LIMIT® Sections method is online available!

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.
