PLASTIC STRESS-STRAIN HISTORY AT NOTCH ROOTS IN TENSILE STRIPS UNDER MONOTONIC LOADING

A comparison of theory with tests on flat, notched specimens of AISI 4340 steel, heat treated, with initial elastic concentration factors of 1.5 to 2.0 shows a systematic discrepancy which is attributed in part to notch strengthening due to triaxial stress. The discrepancy is of the order of 5% for the Neuber theory and larger for the Hardrath-Ohman theory for notch strains of less than 0.015 in./in. and becomes progressively larger for both theories at notch strains in excess of 0.015 in./in. For the mild notches studied here, the Neuber theory has better predictive value.
