Fracture Toughness Determination of Rocks with Core-Based Specimens
Abstract Rock and geomaterial specimens are usually extracted in circular cores. KIc derived from various core specimens is discussed. A newly developed fracture toughness test specimen, semi-circular in shape and contains an edge-crack, is elaborated. The fracture load and the fracture energy of a typical layered rock are measured with static tests, and the fracture toughness is determined using a stress intensity factor method, a compliance method and a J-integral based method. A minimum dimensional requirement is proposed for plane strain fracture toughness. Application of KIc in fragmentation modeling is illustrated. Mixed mode fracture specimen is also presented.
