Lower Strength Steel Brittle Fracture Assessment
Publication: Journal of the Structural Division
Volume 100, Issue 5
Abstract
In designing lower strength steel structures (up to 50 ksi [345 N/mm²] yield strength) subject to low temperatures (down to -60°F [220°K]) information is needed to help define the fracture load of any member with a given crack as a function of temperature. Based on the basic assumption that even after inspection cracks of finite size will exist in a welded structure, an experimental procedure is presented by which the designer can estimate the fracture load of the member. The need for this procedure is apparent from the inadequacies or inapplicability of impact studies and linear elastic fracture mechanics for the grades of steels and range of temperatures of concern. The proposed procedure is substantiated by the results of a previous experimental study. It is shown to be consistent, discriminative, and rational.
