ACL graft migration under cyclic loading

Knee Surgery, Sports Traumatology, Arthroscopy, 2009
AbstractElongation 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, 1985
The 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, 2001
The 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, 1982
Residual 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.

STPZ at Cyclic Loading

2016
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

1979
The 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, 1981
Abstract 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.

Consolidation Theory for Cyclic Loading

Journal of the Geotechnical Engineering Division, 1978
This article presents a one-dimensional consolidation theory for an inelastic normally consolidated clay layer subjected to cyclic loading. Analytic solutions predict the steady-state excess pore pressures and settlements that take place after a large number of cycles.

A Cyclic Load-Test Procedure

1948
In recent years there has been a concerted effort by highway and airport engineers to develop methods of evaluating the supporting power of subgrades, base courses, and finished pavement designs by means of loading or bearing tests. From the investigations and testing programs of the various engineering organizations in charge of pavement design and ...
