The Single-Sample Decohesion Test (SSDT), developed by the authors, eliminates shortcomings of current interfacial fracture toughness testing methods. In this approach, a highly stressed super layer is used to drive delamination and create any mode mix at the crack tip. SSDT uses the change in crack...
