Surface Variable Effects On The Dynamic Properties Of Thoroughbred Horse Racetracks, Christie A. Mahaffey
Surface Variable Effects On The Dynamic Properties Of Thoroughbred Horse Racetracks, Christie A. Mahaffey
Electronic Theses and Dissertations
Historically, equine racing surfaces have been selected and maintained without considering quantifiable data for horse biomechanics or surface mechanical properties. This approach is currently shifting in the racing industry, with an increased interest in understanding the mechanics of the hoof-surface interface to reduce injuries. This dissertation examines three components influencing the hoof-surface interface: 1) correlations between mineralogical composition of dirt tracks, track designs, and climate; 2) the effect of variable cushion depth on dynamic loading, and 3) the effects of different horseshoes on dynamic loading. The second and third pieces of this research are based on an experimental procedure designed …
Explicit Finite Element Modeling Of The Human Lumbar Spine, Milind Rao
Explicit Finite Element Modeling Of The Human Lumbar Spine, Milind Rao
Electronic Theses and Dissertations
Validated finite element (FE) models of the functional spinal unit (FSU) and lumbar spine are essential in design-phase device development and in assessing the mechanics associated with normal spine function and degenerative disc disease (DDD), as well as the impact of fusion and total disc replacement (TDR). Although experimental data from fully intact specimens can be used for model calibration and validation, the contributions from the individual structures (disc, facets, and ligaments) may be inappropriately distributed. Hence, creation of decompression conditions or device implantations that require structure removal may not have the proper resulting mechanics. An explicit FE formulation may …
