    Abstract

    The linear-elastic deformation behavior of the standard chord-supported arc bend, A(B)-C, specimen has been modeled using the finite element method (FEM) in order to generate displacement and compliance data for wide ranges of geometric variables. Using these data, stress intensity factor (SIF) expressions, and crack mouth compliance (CMC) and compliance crack length (CCL) relations have been developed for the A(B)-C geometry. The accuracies of the developed fracture mechanics expressions have been determined with respect to the FEM data and were found to be within ±0.75% maximum. Against data and expressions available in the literature, the accuracies of the developed relations were evaluated and found to be satisfactory.
