This work studies the interfacial toughness of the shipboard Al/Steel structural transition joint (STJ). Instead of using three or four different material properties to represent a real STJ material, only the aluminum and the steel properties are used, and the bi-material interfacial problem is considered in the analysis. With the compact tensile test and the four point bending test, the toughness of the Al/Steel interface can be found. It is found that the interfacial toughness increases as the mode II (Shearing mode) increases. The toughness of the STJ interfaces drop sharply once the heating temperature exceeds 400°C.
