Ahabnet-The trend toward broader application of high-strength structural alloys has increased the potential for failure by low-cycle fatigue crack propagation. There is a signiBcant probability that complex structures will contain undetected cracks remaining from fabrication or that cracks will read

Experiments have been made to investigate the effect of mean stress on fatigue crack propagation in +in. (12.7mm) thick specimens of six aluminium alloys of high and low fracture toughness. The resuits are presented in terms of the stress intensity factor range, AK and the R value where R is the rat
