Effects of frequency and cyclic stress ratio on creep behavior of clay under cyclic loading
Marine Georesources & Geotechnology, 2016ABSTRACTThe mechanical behavior of clay subjected to cyclic loading is important to consider in the design of the foundations of many types of structures that must resist cyclic loading, such as subgrades and offshore foundations, because clay undergoes greater settlement under cyclic loading than under static loading.

Stress ratio effect on cyclic debonding in adhesively bonded composite joints
Composite Structures, 1987A study was conducted to investigate the stress ratio effect on cyclic debond growth behavior in adhesively bonded composite joints. The system studied consisted of graphite/epoxy adherends bonded with a toughened epoxy adhesive. This study showed that the strain energy release rate range was the driving factor for cyclic debonding of the tested bonded

Nonlinear shear mass participation factor (rd) for cyclic shear stress ratio evaluation
Soil Dynamics and Earthquake Engineering, 2004Most methods for assessment of in situ seismic soil liquefaction potential require evaluation of the earthquake-induced cyclic shear stress ratio (CSR). Estimates of the in situ CSR can be developed directly, using dynamic response analyses, but it is common in ‘simplified’ analysis methods to develop estimates of the in situ CSR using empirical ...

On the effect of cyclic stress ratio on the fatigue crack propagation
Engineering Fracture Mechanics, 1975Abstract A new model of fatigue crack propagation is proposed which takes the effect of cyclic stress ratio into account. In the model it is assumed that the fatigue crack propagation rate is proportional to the absorbed hysterisis energy per stress cycle at the tip of a crack.

There exists a critical cyclic stress ratio when sand or clay is subjected to cyclic loading. It is an index distinguishing stable state or failure state. The soil static and dynamic universal triaxial and torsional shear apparatus developed by Dalian University of Technology in China was employed to perform different types of tests on saturated soft ...

AbstractThe installation of dense granular columns by various construction techniques can be used to mitigate liquefaction through a combination of densification, increase of lateral stresses, reinforcement, and drainage. The contributing mechanism of shear reinforcement is isolated and explored using nonlinear three-dimensional (3D) finite-element (FE)

Key components of large structures in aeronautics industry are required to be made light and have long enough fatigue lives. It is of vital importance to estimate the fatigue life of these structures accurately. Since the FCG process is affected by various factors, no universal model exists due to the complexity of the mechanisms.

ABSTRACT In order to investigate the dynamic shear characteristics of rubber sand under cyclic loading, a series of cyclic torsional shear tests was conducted using a hollow cylinder torsional shear apparatus. The effects of four cyclic vertical stress ratios (CVSRs = 0.15, 0.25, 0.35, and 0.45) and four cyclic ...
