The effect of material cyclic deformation properties on residual stress generation by laser shock processing [PDF]
, 2019 Laser shock processing (LSP) is a mechanical surface treatment to induce a compressive residual stress state into the near surface region of a metallic component.

Cyclic behaviours of soft silty clay with long-term traffic loading considering drainage conditions
Frontiers in Built EnvironmentThe traffic loading is a typical cyclic loading with variable confining pressure and always lasts long, and is believed to have a significant effect on the subgrade soil, especially for the subgrade filled with soft clay.

RC column strengthening by lateral pre-tensioning of FRP [PDF]
, 2003 This paper presents a unique strengthening technique for existing concrete columns that use expansive materials to apply lateral pre-tensioning. The technique increases the capacity and ductility of a column as well as achieving better utilisation of the

Cyclic Behavior of Calcareous Sand from the South China Sea
Journal of Marine Science and Engineering, 2021 This study examines the cyclic behavior of calcareous sand obtained from the South China Sea. A series of undrained cyclic triaxial tests were performed on the calcareous sand with various relative densities, cyclic stress ratios, and effective confining

Study on the Cyclic Impact Mechanical Characteristics of Coal under Confining Pressure
ACS OmegaCoal damage accumulation and strength deterioration caused by mining-induced disturbances in deep mines are among the factors influencing the occurrence of dynamic disasters such as rock bursts. To study the mechanical deformation and failure characteristics of coal masses under both cyclic impact and confining pressure, SHPB experiments were performed

Cyclic Undrained Triaxial Strength of Sampled Sand Affected by Confining Pressure
Soils and Foundations, 1981 The effects of confining pressure on the cyclic undrained triaxial strengths of intact sandy specimens obtained by sand sampling methods were investigated. It was found that the ratio of cyclic deviator stress amplitude to initial confining pressure required to cause a certain value of cyclic axial strain amplitude at a certain number of loading cycle ...
