Layered materials, such as sedimentary rocks, are ubiquitous. A newly developed fracture toughness test specimen, which is semi-circular in shape and contains an edge-crack, is subjected to three-point-bend loading. The fracture load and the fracture energy of a layered rock are then measured with s
