Abstract
Early work showed that there was a fracture toughness peak (FTP) as the fracture toughness changed with crack length/specimen width ( a W ). It could be thought of as a “safe crack” for the cracks whose length is smaller than that where the FTP is located. In the present paper, it is indicated that the crack length of FTP is J i- a W curves decreases with increasing yield stress of material and specimen size and decreasing test temperature. The reason for the fracture toughness being insensitive to the ( a W ) for the ultra-high strength and brittle material is explained.
