Photoelastic and theoretical analyses have been carried out to investigate the effect of cracks on the behaviour of two hinged portal frames subjected to two symmetrical vertical concentrated loads. The distribution of internal shear and normal stres

A fracture mechanics model has been implemented in the stiffness matrix method to analyze skeletal structures resting on elastic foundations and containing cracks at superstructure and substructure elements. Stiffness matrices for cracked superstruct

An explanation for non propagating fatigue cracks is presented based on the criterion that once the value of a particular strain intensity factor reduces to the threshold value for the material the crack should stop. Predicted lengths of these cracks

An elastic plastic fracture mechanics solution for short fatigue cracks in smooth and notched specimens is presented which admits plasticity by replacing the conventional stress term with a strain term and accounts for the propagation of very short c

Previous studies have shown that both threshold stress intensity factors and fatigue crack growth rates are dependent on crack size. The average growth rates for very short cracks considerably exceed those given by conventional stress intensity-crack

Elastic and elastic-plastic fracture mechanics solutions are modified to predict the behaviour of short cracks. An effective crack length, l 0 is introduced into the solutions for both the linear elastic stress intensity factor and the J integral. Cr

An important element in fracture control and fracture evaluation of engineering structures is the knowledge of representative material properties. The Mechanical Research Department of Ontario Hydro has a continuing experimental program to determine
