摘要: AbstractThe wide scatter in the results of transverse rupture test on specimens hardmetals same grade, and overlap tests different grades, have. been rationalized by examining fracture surfaces individual specimens. It is found that a major reason for usually initiated at pores other defects various sizes, stress depends defect size according to Griffiths-type relation. This observation considerations concerning position initiation site are used provide quantitative explanation tests; it shown due combined effects variability material variability, consequently does not measure an intrinsic property.
