Thermo-mechanical simulation of a magnetic pulse welding process with first experimental validations

Copper is commonly used in cooling or heating industrial processes especially due to its thermal properties For economicla reasons but also for weight optimization, industry seeks to use other materials such as aluminium. The European H2020 Join'Em project aims at producing bi-materials assemblies with electromagnetic pulse welding (EMW). Two test cases extracted from the Join'em experimental database have been simulated. The methodology and the numerical results are presented hereafter and compared to the experimental results when available.
