Fabrication, Testing And Analysis Of A Fatigue Sensor For Structural Health Monitoring, Subash Gokanakonda Dec 2014

Fabrication, Testing And Analysis Of A Fatigue Sensor For Structural Health Monitoring, Subash Gokanakonda

Dissertations

A novel fatigue monitoring sensor (FMS) is designed, fabricated and tested for detecting and monitoring the fatigue damage and estimating the remaining life of structures and components subjected to cyclic loads. The concept is based on the characteristics of stress / strain life cycle relationship of engineering materials. Sensor consists of alternate slots and strips having different strain magnification factor with respect to the nominal strain. The sensor is designed in such a way that the strips will experience the strain which closely resemble the actual strain distribution in the notch or critical area of the component. The sensor can be ...


Comparative Analysis Of Clavicular Tunnel Confìguration For Coracoclavicular Ligament Reconstruction, Mark Omwansa Dec 2014

Comparative Analysis Of Clavicular Tunnel Confìguration For Coracoclavicular Ligament Reconstruction, Mark Omwansa

Master's Theses

A number of coracoclavicular ligament reconstructions are carried out each year and post surgical fractures of the clavicle have been reported. The primary objective of this research is to develop a comparative metrics that compares clavicular tunnel configurations used in coracoclavicular reconstruction techniques. The goal of this comparison is to reduce post surgical failures due to clavicle fractures. The present analysis compared two techniques { a single 3 mm clavicular tunnel and the other double 6 mm tunnels { experimentally, using Four-point bending testing and Finite Element Analysis (FEA). A unique method, slicing, was used to create an FE clavicle mesh model ...


Subtalar Fusion Fixture Design And Test, Nathan Ortiz Apr 2014

Subtalar Fusion Fixture Design And Test, Nathan Ortiz

Honors Theses

Subtalar arthrodesis is performed when cartilage in the talo-calcaneal (the ankle) joint is degraded in a patient and there are multiple approaches to this surgery. Using synthetic bone material, fixtures were cast from aluminum, using the process of evaporation pattern casting, and epoxy. This casting was used to grip the calcaneus bone of the foot in order to load it mechanically, simulating different scenarios that would be encountered during walking. The relative displacement of the ankle joint was measured using a digital image correlation (DIC) program that was modified to work in both two- and three-dimensional space. This program can ...
