Title:Micro plastic strain hysteresis energy as criterion for fatigue fracture
Author(s):Feltner, C.E.; Morrow, JoDean
Subject(s):Micro-plastic Strain
Fatigue Fracture
Hysteresis Energy
Abstract:In this paper an energy criterion for fatigue failure is postulated. Micro-plastic strain hysteresis energy is considered to be the cause of fatigue damage. On this basis, a relation is developed between stress amplitude and the number of cycles to failure which utilizes only material properties obtained from the static true stress-strain tension test. The analysis is found to compare well with an experimentally determined S-N curve for soft SAE 4340.
