REVIEW OF LIMIT LOADS OF STRUCTURES CONTAINING DEFECTS

A survey of existing limit loads of structures containing defects is given. This is of use in performing a two-criterion failure assessment, in evaluating the J or C parameters by the reference stress approximation, or in evaluating continuum creep damage using the reference stress. The geometries and loadings considered are (by section number): (2) single-edge notched plates under tension, bending and shear; (3) internal notches in plates under tension, bending and shear; (4) double-edge notched plates under tension, bending and shear; (5) short surface cracks in plates under tension and bending; (6) axisymmetric notches in round bars under tension and torsion, and chordal cracks in round bars under torsion and bending; and (7) general shell structures.
