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
Résumé
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.
