Tag: Fracture Fracture Control

Fracture-critical members are treated in the AASHTO LRFD Specifications and in the AASHTO ‘‘Guide Specifications for Fracture Critical Non-Redundant Steel Bridge Members.’’ A fracture-critical member (FCM) or member component is a tension member or component whose failure is expected to result in collapse of the bridge or the inability of the bridge to perform its function. Although the definition is limited to tension

Tag: Fracture Brittle Fracture

Under sufficiently adverse combinations of tensile stress, temperature, loading rate, geometric discontinuity (notch), and restraint, a steel member may experience a brittle fracture. All these factors need not be present. In general, a brittle fracture is a failure that occurs by cleavage with little indication of plastic deformation. In contrast, a ductile fracture occurs mainly by shear, usually preceded by considerable plastic deformation. Design
