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 aK expression which applies for all crack depths. Specimen and loading geometries were suggested for standardized fracturemechanics tests using a round bar.
