Layered metal materials which consist of more than two kinds of metals can have great properties by taking advantage of good property of each metal material. The layered metal materials, however, could include various defects at the interface such as delamination and weak interface stiffness, which can be introduced during rolling and thermal treatment processes. The interface defects could accordingly deteriorate the properties of layered metal materials. Thus, it is important to non-destructively evaluate the interface property before its practical application. In this study, by using a method of resonant ultrasound spectroscopy (RUS), the delamination and the stiffness at interface between two copper sheets are evaluated. The modal analysis is conducted by the finite element method and the resonant frequency is measured by the RUS system.
