In this work, a four-point bend test for determining interfacial fracture resistance is applied to deposited metal layers. The motivating application for this study is a layered manufacturing technique involving the successive deposition of molten metal. A four-point bend test for determining the interfacial fracture toughness of a two-layer bimaterial specimen has been considered in the literature. In this study, this concept is extended and applied to both two-layer and three-layer deposited metal specimens. A closed-form expression for a steady-state energy release rate (independent of crack length) is obtained for the three-layer specimen and is verified by finite element calculations. In addition, finite element results are used to calculate a steady-state measure of mode mix. Experimental procedures for determining the interfacial fracture toughness of deposited metal layers are described for both two-layer and three-layer specimens. Insight is given into specimen design such that interfacial fracture occurs prior to large-scale yielding. Critical interfacial fracture parameters are presented for two deposited metal interfaces and the existence of varying toughness along deposited metal interfaces is discussed.
