Effects of the Change of the Maximum Stress and the Stress Ratio on the Cyclic Creep Behaviors

Bulletin of JSME, 1981
Cyclic creep behaviors of carbon steel are investigated by the true stress controlled low-cycle fatigue tests, stepwise or linearly increasing or decreasing maximum stress with a changing stress ratio. The constitutive equation proposed previously by the authors is found to be applicable to represent the strain accumulations in both increasing and ...

Cyclic creep behavior and life prediction of DZ125 alloy under different stress ratios [PDF]

Journal of Physics: Conference Series
Abstract In order to study the creep behavior and mechanism of DZ125 alloy under cyclic creep under different stress ratios, cyclic creep experiments are performed under a temperature of 850°C and peak stress of 500 MPa, with stress ratios of 0.1, 0.3, 0.5, 0.7, 0.9, and 1, and the mechanical behavior and microstructure of creep samples ...

Effect of Cyclic Stress Level and Overconsolidation Ratio on Permanent Deformation Behaviour of Clayey Subsoil [PDF]

Civil Engineering Journal, 2018
This paper presents the results of a series of one-way cyclic triaxial tests carried out to investigate the role of cyclic stress level and overconsolidation ratio (OCR) on the permanent deformation behaviour of saturated clayey subsoil during long-term cyclic loading.

Depth Reduction Factor Assessment for Evaluation of Cyclic Stress Ratio Based on Site Response Analysis

Soil Mechanics and Foundation Engineering, 2017
This research presents the results of studies in Babol City to develop the depth reduction factor based on equivalent linear analysis of the study area for evaluation of cyclic stress ratio. A total of 35 boreholes (depth 25-35 m) have been drilled. SPT blow counts were taken in each 2 m depth.
