摘要：
A specimen free technique based on kinetic indentation for determination of the fracture toughness of materials is proposed. It is based on the iteration calculation of the specific indentation work which is taken to be equal to the fracture toughness of a material controlled at a defined indentation depth. This technique makes it possible to estimate the degree of embrittlement of materials of long-operating constructions by means of periodic natural nondestructive testing. Examples of the utilization of the technique for steels of nuclear reactor vessels are presented.
