Pore Pressure Development During Cyclic Loading
Journal of Geotechnical Engineering, 1983A mathematical expression is developed for the relationship between the excess pore pressure buildup in sands during cyclic loading and the normalized number of cycles. This expression is based on the equations proposed by previous investigators, but the effects of anisotropic stress conditions are represented more accurately. The new method is capable

Cyclic loading in knee ligament injuries
The American Journal of Sports Medicine, 1980The effect of cyclic loading on knee ligaments was studied both in vivo and in vitro. The compliance of the medial collateral ligaments of athletes participating in hockey, basketball, soc cer, and downhill skiing was determined by using a specially built machine. Tests were conducted before and after partici pation in the various sports.

ACL graft migration under cyclic loading
Knee Surgery, Sports Traumatology, Arthroscopy, 2009AbstractElongation and migration of ACL grafts will lead to a deterioration of the initial stability of ACL reconstructions. The graft migration has been sparsely investigated independently from the elongation of the graft–fixation complex. The hypothesis of this investigation was that cyclic tensile loads cause a measurable migration of the grafts ...

Cyclic Axial Loading of Spinal Implants
Spine, 1985The performance characteristics of Harrington distraction rods were evaluated and compared with paired wired L-rods when subjected to cyclic axial compression loading. Twelve fresh frozen swine spines with intact facet joints and anterior and posterior ligamentous complexes were instrumented and tested in a specially designed pneumatic testing device ...

Damage of Marble from Cyclic Loading
Journal of Materials in Civil Engineering, 2001The behavior of marble was investigated to evaluate the damage and failure mechanisms produced from cyclic loading. Approximately 100 cycles of increasing load steps, representing low cycle fatigue, were imposed on beams in three and four-point bending. Damage was recorded through an array of strain gauges and an interferometric technique that provided

Residual Undrained Deformation from Cyclic Loading
Journal of the Geotechnical Engineering Division, 1982Residual undrained deformation of anisotropically consolidated soil samples under cyclic loading is investigated. The magnitude of residual deformation is influenced by factors such as initial stress condition, excess pore pressure generated by the cyclic loading, and soil properties.

For structures that are subjected to cyclic loading above their elastic limits, the phenomena mentioned in Chap. 2 are important for their lifetime, in particular, the elastic-plastic strain ranges and the accumulated strains resulting from a possible ratcheting mechanism.

Cyclic Pile Load Testing—Loading System and Instrumentation
1979The scope, concepts, methodology, and details of a load application system and instrumentation for the successful operation of a series of cyclic pile load tests are described. The purposes of the pile tests on an instrumented H-pile were to evaluate the dynamic behavior of piles under cyclic loading conditions for seismic analyses and ...

An Electropneumatic Cyclic Loading System
Geotechnical Testing Journal, 1981Abstract This paper reviews some of the current systems in use for the application of cyclic loads to soil specimens. Their main features and principles of operation are described. A relatively low-cost electropneumatic system recently developed at the University of California at Berkeley is described in detail.
