Dynamic Fracture Toughness of Modified SA508C12 in the Ductile-to-Brittle Transition Region

Source

Fracture toughness testing of steels in the ductile-to-brittle transition region is complicated by a high degree of data scatter. Variations in the amount of ductile tearing prior to cleavage initiation often accompany the data scatter. Dynamic toughness testing is shown to be experimentally successful at reducing the incidence of prior ductile tearing. For the displacement rates tested, dynamic toughness values are at or above the lower-bound static toughness. Analysis of transition region toughness data using Weibull statistics, available energy analysis, and a constraint correction procedure is discussed.
