Monopiles subjected to uni- and multi-lateral cyclic loading [PDF]

, 2017
Offshore wind turbines are subjected to significant environmental loads from a combination of current, wind and wave action. Under such conditions, the directions of these environmental loads vary over the service life of the structure and therefore the ...

Strength degradation of sandstone and granodiorite under uniaxial cyclic loading

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Change in mechanical properties of rocks under static loading has been widely studied and documented. However, the response of rocks to cyclic loads is still a much-debated topic.

Bearing behavior and accumulated rotation of modified suction caisson (MSC) in saturated sand under cyclic loading

Rock and Soil Mechanics, 2021
Modified suction caisson is a new type of suction foundation for offshore wind power engineering. Model tests were carried out to investigate the variation of cumulative rotation angle and its influencing factors of the regular suction caisson (RSC) and

Analysis Deformation Failure Characteristics and the Energy Evolution of Varying Lithologies under Cyclic Loading

Geofluids, 2022
Deep underground engineering often utilizes cyclic loading. To understand the deformation and damage characteristics of rock under cyclic loading conditions, cyclic loading tests of three different specimens with varying lithology were performed.

Mechanical behaviour of medium-grained sandstones exposed to differential cyclic loading with distinct loading and unloading rates

Journal of Rock Mechanics and Geotechnical Engineering, 2022
This work aims to investigate the mechanical behaviour of medium-grained sandstones under cyclic loading with different loading/unloading rates. This type of cyclic loading is called differential cyclic loading (DCL) and is considered for testing rock ...
