Abstract

The elastic compliance is determined for the configuration of the line slot terminated by circular holes and for the elliptical cut-out in a finite-width sheet specimen loaded in tension. Comparisons are then made with real cracks to ascertain the extent of equivalence with respect to strain energy release rates and compliance for the two configurations selected.
