Multi-material designs are becoming increasingly important in the push towards light weighting of automotive and aerospace structures for energy efficiency. The joining of dissimilar materials is a crucial aspect in such multi-material designs. Conventional welding techniques face challenges primarily because of vastly different thermal properties of the constituent components. Alternates such as fasteners and adhesives provide reduced joint efficiency. High velocity impact welding (HVIW) by vaporizing foil actuators provides a promising alternate.
The main objective of this work is to get a predictive understanding of the joint properties based on the joint morphology and interfacial characteristics obtained in the HVIW. The joint characteristics, including local temperature and strain, are in turn obtained from a validated finite element method based model simulating the process.
