P … WebThis is done by conducting an appropriate set of fracture mechanics based experiments. Test specimens that we commonly use include the double cantilever beam, end notch flexure, and four-point bend geometries (Figure 2). Other experiments may be employed depending upon the nature of the interface being tested. We present two examples below.
