✦ Synopsis

The present investigation is focused on high cycle fatigue life prediction based on material property of the workpiece. A new approach based on industrial tool life data was introduced for estimation of fatigue properties of the tool material. The effect of the strength coefficient K and strain hardening exponent n of four different workpiece materials was included in the local stress and strain approach to derive a simple relationship between the high cycle fatigue life and material property of the workpiece. According to this relationship, a reasonably reliable high cycle fatigue tool life can be estimated.
