Experimental Study on Seismic Compression of Chinese Loess under Cyclic Direct Simple Shear Testing
Advances in Civil Engineering, 2022 Seismic compression is the accumulation of contractive volumetric strains in unsaturated soil from earthquake shaking. For Chinese loess, the behavior of seismic compression is extremely significant and has been recognized in historical earthquakes. As a

Comparison of cyclic compression, cyclic distraction and rigid fixation: Bone healing in rabbits [PDF]
Acta Orthopaedica Scandinavica, 1998 A tibial osteotomy was created in rabbits and was fixed with an external fixator. The rabbits were divided into 3 groups in which cyclic distraction, cyclic compression and rigid fixation were applied. Fracture healing was similarly enhanced in the groups with cyclic compression and cyclic distraction.

Cyclic constitutive equations of rock with coupled damage induced by compaction and cracking
International Journal of Mining Science and Technology, 2022 In this paper, the cyclic constitutive equations were proposed to describe the constitutive behavior of cyclic loading and unloading. Firstly, a coupled damage variable was derived, which contains two parts, i.e., the compaction-induced damage and the ...

Regulation of subchondral bone osteoblast metabolism by cyclic compression [PDF]
Arthritis & Rheumatism, 2012 Abstract Objective Recent data have shown that abnormal subchondral bone remodeling plays an important role in osteoarthritis (OA) onset and progression, and it was suggested that abnormal mechanical pressure applied to the articulation was responsible for these metabolic changes.
