As a result of the joining process, metal composites with unique bond characteristics and exceptional material features can be manufactured. There is limited knowledge on the mechanical properties of the explosively welded bond and its influence on the structural and fatigue strength of the composites. The present paper aims to investigate the fatigue life and failure mechanism in explosively welded metal composites under cyclic tensile loading. In this study, the three-layer clads consisting of steel, copper, and tantalum were examined. Fatigue testing was performed with the loading asymmetry ratio R=0.02. Optical microscopy was used to locate the primary crack origin after testing. It was established that depending on the wave height of the interface the primary cracks can originate at different locations. © 2021 The Authors. Published by ELSEVIER B.V.
