Characterization of solid-fluid mixtures
(Texas A&M University, 2000)
In this work we develop and investigate a mathematical model for the description of the mechanical behavior of soft, hydrated tissues with significant perfusion. We set up and derive the mathematical description and balance ...
A framework for assembly sequence planning for computer aided design of mechanical assemblies
(Texas A&M University, 2000)
This thesis presents a framework for interactive assembly sequence panning for mechanical assemblies. Realizing the utility of such a tool that will enable the product engineer to evaluate the assemblability of his designs ...
Vibration suppression of laminated composite plates using embedded smart material layers
(Texas A&M University, 2000)
In this study, a complete theoretical formulation of laminated composite plates with integrated smart material layers that serve as sensors and/or actuators is presented for the vibration suppression of laminated composite ...
Heat transfer measurements in a two-pass square duct via a transient liquid crystal image method
(Texas A&M University, 2000)
In this research air flow transient heat transfer in a two-pass channel via thermochromic liquid crystals is studied. An 180° turn and rib roughened surface are part of the channel. This geometric combination simulates ...
A comparison of rotordynamic-coefficient predictions for annular honeycomb gas seals using different friction-factor models
(Texas A&M University, 2000)
Predictions of rotordynamic-coefficients for annular honeycomb gas seals are compared using different friction-factor models. Analysis shows that the fundamental improvement in predicting the rotordynamic-coefficients ...
Position control of a servopneumatic system using fuzzy compensation
(Texas A&M University, 2000)
The position control of a servopneumatic system in the presence of stick-slip type of friction is investigated. A cost effective, model-free fuzzy compensation scheme is proposed. The fuzzy compensation scheme compensates ...
Caged Molecular Fluorescence Velocimetry to measure meso-to micro-scale thermal flow fields
(Texas A&M University, 2000)
A caged molecular fluorescence velocimetry (caged MFV) system has been developed to measure velocity profiles of thin meniscus flow fields commonly established in micro-scale thermocapillary devices such as micro heat pipe ...
Force measurements in magnetic bearings using fiber optic strain gauges
(Texas A&M University, 2000)
The research presented here develops a new method for measuring forces in magnetic bearings. Fiber-optic strain gauges (FOSGs) mounted to the side of the magnet poles are used to detect the small levels of strain that the ...
Experiments to model the rotordynamic behavior of rub rings and bumpers
(Texas A&M University, 2000)
Rub-impact between rotors and stators is a widely studied phenomenon due to its deleterious effects on rotating machinery. When large amplitudes of vibration are developed in rotors due to either imbalance or triggered ...
Ultrasonic measurement of residual stress relaxation in welded steel plates using critically refracted longitudinal waves
(Texas A&M University, 2000)
This study investigates whether or not there is a measurable amount of residual transverse stress relaxation in welded steel. This was determined by using two different methods of stress measurement. These methods involved ...
