Abstract:

A new combination of the Neuber parameter and stress-strain data is proposed and investigated for a completely general graphic analysis of cycle-by- cycle notch stress level. The proposed analysis is applied to two common aircraft structural materials, 2024-T4 and 7075-T6. Life to failure predictions based on the graphically derived notch stress levels compare very favorably with constant stress amplitude notched coupon results.
