title = "Experimental Measurements of Interface Fracture Toughness Using Double Cantilever Bending",
abstract = "Fracture properties at the interface of hard and brittle Alumina (Al2O3) coating over a soft Al (Al 6061) substrate are studied using the double cantilever bend (DCB) test. These coatings were thermally sprayed and included substantial porosity. Elastic properties of the Alumina layer were determined by three-point bending (3PB) of the coated specimens. Fracture energy of Alumina was determined using a notched sample of the free-standing Alumina coating. FEM analysis of DCB was performed to estimate the stress intensity factor at the crack tip along the Al/Al2O3 interface. The experimental results show mixed mode fracture behaviour in most of the coatings. Average fracture energy of the interface, 6.46 J/m2, was estimated using these measurements.",
