No satisfactory explanation of the fatigue mechanism of metals has yet been advanced. The generally accepted idea involving work-hardening and subsequent ‘brittle’ fracture cannot be substantiated by observation as being the only cause of fatigue failure. Observations I have made on pure aluminium and aluminium–½ per cent silver specimens have shown that the mechanisms of failure at high and low stresses are fundamentally different1.
