Multiaxial creep–Fatigue Life using cruciform specimen
International Journal of Fatigue, 2007Co-Authors: Shengde Zhang, Kunimasa Ozaki, Masaya Harada, Masao SakaneAbstract:Abstract This paper studies the multiaxial creep–Fatigue Life for type 304 stainless steel at elevated temperature. Strain controlled biaxial tension–compression creep–Fatigue tests were carried out using cruciform specimens under four strain waves at three principal strain ratios. The strain wave and the principal strain ratio had a significant effect on creep–Fatigue Life of the cruciform specimen. The creep–Fatigue Life ratio decreased as the principal strain ratio increased which indicates that larger creep damage occurred at larger principal strain ratio. The effects of the strain wave and principal strain ratio were discussed in relation to the observations of surface crack and void area density in the gage part of the specimen.

Effect of Hydrostatic Stress on Low Cycle Fatigue Life
Volume 1: Codes and Standards, 2005Co-Authors: Masao Sakane, Takamoto ItohAbstract:This paper overviews the effect of hydrostatic stress on the static tensile stress-strain relationship, low cycle Fatigue Life, creep rupture time and creep-Fatigue Life at room and elevated temperatures. There was almost no influence of the hydrostatic stress on the tensile stress-strain relationship but the tensile ductility was increased by the hydrostatic stress. Small or little increase of Fatigue Life was observed by the superposition of the hydrostatic stress under a full reversed loading but a clear increase of Fatigue Life was found in a zero-to-tension loading. The hydrostatic stress significantly lowered the creep strain rate and elongated the creep rupture time. The hydrostatic stress also increased the creep-Fatigue Life under a full reversed loading.Copyright © 2005 by ASME

Probabilistic Fatigue Life prediction of multidirectional composite laminates
Composite Structures, 2005Co-Authors: Sankaran MahadevanAbstract:A new damage accumulation model for Fatigue Life prediction of composite laminates is proposed in this study. The model is constructed on the ply level and uses a new multiaxial damage index to consider the damage caused by different stress components. The Fatigue Life is predicted based on the proposed model and experimental results of the unidirectional laminates. The numerical results are compared with the experimental data for balanced laminates. The predicted Fatigue lives agree with the experimental observations very well. The methodology for probabilistic Fatigue Life prediction and reliability calculation is also presented.
