OVERSTRAIN EFFECTS DURING VARIABLE AMPLITUDE SERVICE HISTORY TESTING

A technique of editing a service strain history, to omit strain cycles below various threshold levels, has been used to determine the damage caused by each level of strain cycles in a variable amplitude loading history applied to hot-rolled g40.21-50a steel. Three service history programmes were used: Ford, Deere and GM. The results obtained indicate the presence of an overstrain effect much larger than has been previously observed. (Author/TRRL)
