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
A general defioition of fracture toughness, designated by 6, is developed which is appropriate to situations of subcritical crack growth and/or kvge-scalc crack border plastic yield. The theoretical basis as well as comparisons with other proposed measures of fracture toughness are also discussed. A
