    摘要： A method for measuring the tenacity Kc of a material, wherein a cuboid test piece of the material with a central hole is placed between two jaws of a compression testing device, each of said jaws pressing on a far end of the test piece. The two jaws apply a force to each of the ends until the test piece fails completely. Variations of the applied compression force applied at each end of the test piece are measured as a function of the time, during compression. The maximum value F0 of said compression force is determined. Three distinct zones are marked on the surface of one of the failure surfaces. A distance is measured L0 between the edge of the hole and a transition line separating the second zone from the third zone, and the parameter Kc is calculated as a function of the force F0 and the distance L0.

    摘要： A compact pipe specimen applicable to a fracture toughness test used to evaluate physical properties of a pipe material is provided. The compact pipe specimen includes: a pipe having a notch portion formed in a circumferential direction and a crack portion formed at the edge of the notch portion; and first and second jigs having openings to which a pressurizing unit is coupled so as to cause a bending load on the pipe, having the notch portion therebetween, and attached to the exterior surface of the pipe, respectively. It is unnecessary to correct the influence of a constraint effect due to varying sizes and shapes of the specimen. There is no restriction to the curvature and thickness of a pipe. A fracture behavior of a pipe crack portion can be precisely simulated.
