A study of contact between a profile meter stylus and polymer films on roughened substrates
(Virginia Tech, 1985-12-05)
Viscous solutions for the Navier Stokes equations using an upwind finite volume technique
(Virginia Tech, 1988-05-05)
The process of enhancing an upwind finite volume, two-dimensional, thin layer Navier Stokes solver to achieve complete Navier Stokes solutions is described. The shear stress and heat flux contributions are identified and ...
Adaptive control of a four-bar linkage
(Virginia Tech, 1985-04-05)
<p>Three discrete-time adaptive controllers are developed and applied to Four-bar linkage velocity control to reduce the input link velocity fluctuations without compromising the control system velocity transient response. ...
Stress-density relationships for an agricultural soil
(Virginia Tech, 1987-04-05)
<p>Triaxial tests under high loading rates and different confining pressures simulate the multi-pass effect of a tractor wheel loading on the soil. A volume measuring technique was developed to be used in triaxial tests ...
Application of the finite element method in high-side gondola rail car design
(Virginia Tech, 1987-10-14)
<p>Finite element models of four design configurations of a proposed composite aluminum-steel high-side coal gondola rail car were developed. The designs were analyzed for compliance with the loadings set forth by the ...
Development of a [i.e. an] engineering design procedure for a complex revolute joint
(Virginia Tech, 1988-12-15)
<p>Design procedures are developed that combine both the finite element method and the transfer matrix method in design. These procedures were drawn up as a result of the analysis of a large continuous mining machine ...
Uncooled choked plasma torch for ignition and flameholding in supersonic combustion
(Virginia Tech, 1986-08-05)
An experimental investigation on an uncooled choked plasma torch using hydrogen/argon mixtures as a propellant was conducted. This low-power plasma torch was designed to be used as an ignitor and flameholder in supersonic ...
Synthesis and design of the RSSR spatial mechanism for function generation
(Virginia Tech, 1985-08-05)
<p>The purpose of this thesis is to provide a complete package for the synthesis and design of the RSSR spatial function generating mechanism.</p> <p> In addition to the introductory material this thesis is divided ...
Heat transfer during pulsed laser cutting of thin sheets
(Virginia Tech, 1989-05-05)
<p>A numerical model of the temperature field during pulsed laser cutting of thin sheets (approximately 2.5 x l0<sup>-5</sup> m) was developed. Cutting was simulated through removal of nodes from a finite difference ...
Oxygen transfer in recirculating flow
(Virginia Tech, 1985-01-15)
<p>An experimental investigation was done on oxygen transfer into a laminar flow of whole blood and saline solutions downstream of an abrupt pipe expansion. This was used as the experimental model for regions of separated ...
