Effect of Cyclic Loading Frequency on Liquefaction Prediction of Sand

open access: yesApplied Sciences, 2020
The frequency of ground motions during earthquakes is typically in the order of a few hertz. As the earthquake-induced liquefaction of soils is widely assessed by performing laboratory tests, it is necessary to consider various loading frequencies ...

A Frequency Regulation Strategy for Wind Power Based on Limited Over-Speed De-Loading Curve Partitioning

open access: yesIEEE Access, 2018
Over the past decade, wind power has rapidly developed, bringing great challenges to power system frequency control. To enable wind turbines (WTs) to operate with independent frequency regulation similar to that of synchronous generators, the development

Examination of the Effects of Different Frequencies on Rock Fracturing via Laboratory-Scale Variable Amplitude Fatigue Loading Experiments

open access: yesApplied Sciences, 2023
In this study, the characteristics of the fracture evolution of argillaceous shale under increasing-amplitude loading were investigated. The GCTS RTR-2000 test system and in-situ acoustic emission (AE) monitoring were employed to execute the tests.

Study of High-cycle Fatigue Properties in Bovine Tibia Bones based on Reliability and Scatter-band Predictions [PDF]

open access: yesMechanics of Advanced Composite Structures, 2020
Bones are natural composites, which are consisted of mineral fibers, which strengthen the organic matrix.  Such composites are exposed to both monotonic and cyclic loadings, which could predispose the structure to failure.

A Thorough Investigation of the Dynamic Properties of Granite under Cyclic Loading

open access: yesApplied Sciences, 2023
We propose a novel inverse analysis method that utilizes shockwaves to detect the operational condition of tested rock. To achieve this back analysis, an in-depth investigation of the dynamic properties of granite specimens was conducted.
