mixed clayey soils occur as mixtures of sand (or gravel) and clay in widely varying proportions. their engineering behavior has not been comprehensively studied yet. an experimental program, comprising monotonic, cyclic, and post-cyclic triaxial tests was undertaken on compacted clay-granular material mixtures, having different proportions of clay and sand or gravel. this paper presents the res...

Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...

objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...

in this paper, the effect of cyclic loading on punching strength of flat slabs strengthened with carbon fiber reinforced polymer (cfrp) sheets is studied. experimental results of ten slab specimens under monotonic and cyclic loading are analyzed. eight specimens were strengthened with cfrp sheets on the tensile face of the slabs and the two other specimens were kept un-strengthened as control s...

in this study, a researching program is conducted by cyclic triaxial test to determine the post-cyclic behavior of bushehr carbonate sand retrieved from the north of the persian gulf, under anisotropic consolidation at 200 kpa confining pressure. the article compares the post-cyclic monotonic strength and excess pore water pressures generated after the test with the pre-cyclic monotonic results...

this paper presents the results of a series of monotonic and post-cyclic triaxial tests carried out on a clay specimen and three types of clay-sand mixed specimens. the focus of the paper is on the post-cyclic mechanical behavior of the mixed specimens, as compared to their monotonic behavior. analyses of the tests results show that cyclic loading degrade undrained shear strength and deformatio...

carbonate materials are mostly found in tropical areas, where exploiting gas and oil resources are of high concern. their unique behavior under shear loading first was recognised during oil resources investigations in the persian gulf. off-shore structures have been placed on carbonate soils which are highly crushable.during storms cyclic loading imposes on the bases of structures lied down on ...

objective: endothelium is a selective and permeable membrane for transferring nutrients and vital components to arterial wall. endothelial damage might lead to altered biological function of endothelium and clinical consequences such as atherosclerosis. blood pressure pulse always exerts circumferential tension to the arterial wall. hence, such tension together with other loads, play important ...

introduction: endothelial cells are subjected to mechanical forces caused by pulsatile flow and pressure leading to hemodynamic shear stress and circumferential stress on endothelial layer. the study aimed at a quantitative evaluation of endothelial cell morphology by application of cyclic loading. endothelial cells respond to applied loads with adaptation and remodeling. such mechanisms are ma...

experimental study of the cyclic behavior of unsaturated materials is more complex than that of the saturated materials due to the required equipment, experience and time. furthering investigations in the field of unsaturated materials is necessary to better understand its complexity and sensitivity of unsaturated cyclic parameters to different determinants such as suction path, stress path, lo...
