Wide Range Stress Intensity Factor Expression for an Edge-Cracked Round Bar Bend Specimen

Abstract

An edge-cracked round bar was analyzed for use as a fracture mechanics test specimen. Shallow and deep crack limit solutions were developed and combined with experimental and numerical results to obtain K expressions which apply for all crack depths. Specimen and loading geometries were suggested for standardized fracture mechanics tests using a round bar. Keywords: Fracture testing, Limit solution, Bend specimen, Cylindrical geometry, Cracks.
