“…It is evident that the relative scatter of fracture toughness values (which is assessed as a coefficient of variation D M, where D is the variance, M is the expectation function of K f or K c I ) upon TPL is smaller than that in standard tests. This conclusion reasonably agrees with the known experimental findings [4,15,27,28].…”

Probabilistic definition of local criterion for brittle fracture under complex thermomechanical loading

The new local criterion for brittle fracture in probabilistic definition, which was used by the authors earlier for the K Ic (T) prediction, is modified for the case of non-isothermal non-monotonic loading. An approach is put forward which allows predicting the brittle fracture probability for cracked elements under complex thermomechanical loading typical, for example, of the case of emergency cooldown of a reactor pressure vessel. The approach has been verified by comparing the calculated and experimental data of assessment of the influence of various thermomechanical pre-loading modes on the fracture toughness of reactor pressure vessel steels.
