Cyclic strength of loose anisotropically-consolidated calcareous sand under standing waves and assessment using the unified cyclic stress ratio

Engineering Geology, 2021
Abstract Progressive and standing waves can produce instability of the seabed and seabed-supported marine structures. In this paper, the stress paths induced by standing waves were deduced to provide a theoretical basis for laboratory element tests to establish the cyclic behavior of marine sediments, which can serve to improve the understanding of ...

Critical cyclic stress ratio of undisturbed saturated soft clay in the yangtze estuary under complex stress conditions

Transactions of Tianjin University, 2010
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 ...

Stress ratio effect on cyclic debonding in adhesively bonded composite joints

Composite Structures, 1987
A 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

Cyclic stress ratio of landslide deposits in Vinodol Valley, Croatia

Proceedings of the 4th Regional Symposium on Landslides in the Adriatic - Balkan Region, 2019
Earthquakes are among the most significant landslide triggering factors. Earthquake induced vibrations produce small cyclic shear strains, and the resulting cyclic stresses gradually increase pore pressure. The Vinodol Valley is characterized by numerous relatively small and shallow debris slides, initiated in eluvial deposits, or along the contact ...

Effects of frequency and cyclic stress ratio on creep behavior of clay under cyclic loading

Marine Georesources & Geotechnology, 2016
ABSTRACTThe 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.

On the effect of cyclic stress ratio on the fatigue crack propagation

Engineering Fracture Mechanics, 1975
Abstract 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.
