Cyclic fatigue damage characteristics observed for simple loadings extended to multiaxial life prediction

  title={Cyclic fatigue damage characteristics observed for simple loadings extended to multiaxial life prediction},
  author={David J. Jones and P. Kurath},
Fully reversed uniaxial strain controlled fatigue tests were performed on smooth cylindrical specimens made of 304 stainless steel. Fatigue life data and cracking observations for uniaxial tests were compared with life data and cracking behavior observed in fully reversed torsional tests. It was determined that the product of maximum principle strain amplitude and maximum principle stress provided the best correlation of fatigue lives for these two loading conditions. Implementation of this… Expand
The relationship between observed fatigue damage and life estimation models
Observations of the surface of laboratory specimens subjected to axial and torsional fatigue loadings has resulted in the identification of three damage fatigue phenomena: crack nucleation, shearExpand
Fatigue damage prediction in multiaxial loading using a new energy-based parameter
Abstract A new approach for the definition of the critical plane and a new energy-based multiaxial fatigue parameter are proposed in this work. The normal strain energy and shear strain energy on twoExpand
