 note = {The “critical rate” is defined as the probability of occurrence of fracture of materials under applied stress. The “safty rate” is also defined as the probability which is equal to the unity minus the critical rate. Thus, the terminology “safty factor” is criticized. The critical rate for the body having many components of stress and for the anisotropic body, is also discussed. The probability distribution of the ratio of the stress of fracture to the available stress is briefly mentioned.},
