Advances in acoustic stress characterization.
(1998)Another effort in this study is devoted to employing Rayleigh waves with a line-focused acoustic microscope to characterize the through-thickness residual stress distribution. Assuming the principal strain directions are ... -

Analysis and control of thermoelastic vibrations in plate structures.
(2001)This work is concerned with the analysis and control of thermoelastic vibrations in rectangular plate structures using piezoelectric materials for the sensor(s) and actuator(s). Both isotropic and symmetrically laminated, ... -
Analytical solutions for a continuum, parallel-plate, electrostatic probe /

Blowoff characteristics of partially premixed flames of prevaporized blends of biofuels and petroleum fuels
(2017-12-15)The laminar partially premixed flames of prevaporized Jet A, canola methyl ester (CME), palm methyl ester (PME), soy methyl ester (SME), and blend flames of Jet A and CME-PME-SME were studied over a range of equivalence ... -
Buckling and flexural vibration of rectangular plates subjected to half sinusoidal load on two opposite edges.
(2004)The problem of buckling of thin rectangular plates subjected to uniform and linearly varying in-plane load has been solved quite some time back beginning with the work of Bryan in 1890--91. Recently, Leissa and Kang obtained ... -
Computation of vibration modal shapes and natural frequencies of a general, orthotropic-laminated, thin shell using finite elements /
(The University of Oklahoma., 1971) -
Design and Performance Evaluation of a Retractable Wingtip Vortex Reduction Device
(2019-12)As an airfoil achieves lift, the pressure differential at the wingtips trigger the roll up of fluid which results in swirling wakes. This wake is characterized by the presence of strong rotating cylindrical vortices that ... -
Development of helicopter attitude axes controlled hover flight without pilot assistance and vehicle crashes.
(2007)In this work, we show how to computerize a helicopter to fly attitude axes controlled hover flight without the assistance of a pilot and without ever crashing. We start by developing a helicopter research test bed system ... -
Drag characteristics for a compliant surface airfoil /
(The University of Oklahoma., 1971) -
Effects of elliptical burner geometry on partially premixed gas jet flames in quiescent surroundings.
(2005)The 3:1 AR elliptical and circular burners produced similar carbon monoxide and nitric oxide emission indexes over the range of equivalence ratios of 0.55 to 4.0, for laminar flames. (Abstract shortened by UMI.) -
Error estimation and structural shape optimization.
(1998)This work is concerned with three topics: error estimation, data smoothing process and the structural shape optimization design and analysis. In particular, the superconvergent stress recovery technique, the dual kriging ... -
An experimental and numerical investigation on hydrogen-hydrocarbon composite fuel combustion.
(2000)Experimental measurements and numerical predictions show that the local flame temperature increases with the increase of hydrogen content in the mixture; consequently the NO production increases in the flame. On the other ... -
Experimental and Numerical Studies on the Structural Dynamics of Flapping Beams
(2015-05)The nonlinear structural dynamics of slender cantilever beams in flapping motion is studied through experiments, numerical simulations, and perturbation analyses. A flapping mechanism which imparts a periodic flapping ... -
Forces and energy transfer induced by rarefied plasma flows past solid bodies /
(The University of Oklahoma., 1972) -
Free vibrations of orthotropic conical sandwich shells with various boundary conditions /
(The University of Oklahoma., 1969) -
High-fidelity modeling and impact footprint prediction for vehicle breakup analysis.
(2005)Thus the main thrust of this study was to develop and verify the additional dynamics modeling and capabilities for the analysis tool with the objectives to (1) have the capability to predict impact point and footprint, (2) ... -
Hot Surface Ignition Properties of Pre-Vaporized Jet-A and Biodiesels
(2017-05)In the search for more environmentally friendly energy sources, biofuels have emerged as an attractive alternative to traditional petroleum fuels. In addition to being close to carbon-neutral and renewable, biofuels have ...
