Numerical Prediction of Stresses at High Temperature of 3rd Generation Advanced High Strength Steels During Resistance Spot Welding - Liquid Metal Embrittlement Risk Assessment. Methodology to Create and Validate a Reliable and Robust Numerical Material Card

Abstract

The prediction of stress level during Resistance Spot Welding at high temperature is very useful to reduce and/or avoid Liquid Metal Embrittlement phenomenon. However, the experimental estimation of stress level into metal sheets during a Resistance Spot Welding process is impractical. Therefore, a numerical methodology to predict mechanical stresses, using more accessible experiments, is proposed in this work.
