The well known approximation formulas valid for uniaxial notch stresses are extended to multiaxial stress states in order to establish a load - equivalent notch stress and strain relationship. The correlation between equivalent and principal notch stresses and strains is obtained by applying theory of plasticity in combination with an assumption concerning one stress or strain component. The approximation method is summarized in a solution scheme. Finally aspects of accuracy are discussed.

Plastic Loading

This article describes an investigation into the ability of a number of different fracture mechanics approaches to predict failure by brittle fracture under general elastic/plastic loading. Data obtained from C(T) specimens of A508 ferritic steel subjected to warm pre-stressing and side punching were chosen as such prior loadings produce considerably non-proportionality in the resulting stress states. In addition, failure data from a number of round notched bar specimens of A508 steel were considered for failure with and without prior loading. Failure prediction, based on calibration to specimens in the as received state, was undertaken using two methods based on the J integral and two based on local approach methodologies.
