AbstractSeveral constitutive models for sands are based on an additive split of the effective stress rate into two terms. One term accounts for the deviatoric stress ratio $$\varvec{r}$$ r , the other for the mean effective stress $${p}$$ p ...

Civil Engineering structures are constantly subjected to environmental forces and changes around the surroundings hence a strong need for assessment of the interaction and predictive measures that lead to pro-active actions towards the structural safety and health monitoring.

Influences of stress ratios and stress cycle frequencies on cyclic stress corrosion crack growth characteristics of a high-strength steel have been investigated. The influences of stress ratios on crack growth rate under cyclic SCC are clearly distinguished between above and below KISCC. In the range of Kmax, KFSCC≤ Kmax < KISCC, a decrease of R causes

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

Including the normal to shear stresses ratio in fatigue life estimation for cyclic loadings [PDF]
The paper presents the estimation of the fatigue life under multiaxial cyclic loading of two construction materials. The main aim of this paper is to present a new method which allows evaluation of fatigue life during the design and construction phase of machine elements. In paper three well known multiaxial fatigue criteria based on the critical plane

Cyclic creep behavior and life prediction of DZ125 alloy under different stress ratios
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 ...

Presented test results on transverse cracking in cross-ply laminates upon tension–tension cyclic loading show that the increase of crack density depends not only on the maximum transverse stress in the cycle but also on the local cyclic stress ratio RTloc in the analyzed layer.

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

Various constitutive formulations have been developed over the years to reproduce the cyclic resistance of sands. A common challenge for existing models is the accurate simulation of the cyclic strength of sands for a wide range of initial conditions and different cyclic stress levels when adopting a single calibration. Many liquefaction models tend to
