Abstract:

The paper presents a linear cumulative damage theory, macroscopically considering elastic and plastic straining, and accounting for biaxiality through the von Mises theory for combined strains. Experimentation on SAE 4340 steel alloy supported this damage hypothesis and confirmed the associated exponential relationship between elastic strains with cyclic life and plastic strains with cyclic life. A limited evaluation of an aluminum casting material, C-355-T61, also supported this exponential dependency. Notching did not significantly alter this low cycle fatigue behavior.
