A procedure for designing against fatigue failure of notched parts is presented. It is based on measuring nominal loads or strains and estimating notch root stresses and strains using Neuber's rule. Other inputs to the procedure are axial smooth specimen cyclic stress-strain response, fatigue properties, and fatigue notch factor. Miner's cumulative damage rule is applied to the local stress-strain history and fatigue life predicted. Examples are given where life predictions are compared to laboratory test results.A procedure for designing against fatigue failure of notched parts is presented.
