✦ Synopsis

A new hypothesis is presented for dete~ining the mixed-mode fracture toughness criterion of brittle materials such as rocks, cement and ceramics. The obtained criterion gives a reasonable result, which is in good agreement with published data. The data, obtained here for mixed-mode fracture toughness of flyash cement paste, confirm also the use of the hypothesis for the problem of fracture toughness, including negative &.

A prediction of the direction of incipient crack growth in brittle-like materials and the associated fracture loci under mixed mode loading is proposed. It is postulated that the direction of unstable crack propagation is determined by the "weakest" near-tip element defined as the one which would re

Based on the combined micro-and macro fracture mechanics, the two requisites necessary for the crack propagation, that is, the energy unstable requisite and the critical local stress requisite, are derived for the low-stress brittle fracture of notched specimens. Thus the fracture criterion was obta
