Abstract

An experimental technique using sandwiched Brazil-nut specimens to quantitatively characterize interfacial fracture toughness over a wide range of phase angles is presented. Specimens are made by sandwiching a thin layer of adhesive material between two metal substrates. Tensile loads are applied to the specimens at various loading angles. Through the use of fracture mechanics and finite element analysis, interfacial fracture toughness as a function of loading phase angle is determined from the experimentally obtained critical load and loading direction. The fracture toughness curves for several different Cu/adhesive systems are obtained.
