Effect of fluid inertia on squeeze film damper force response
(1985)
The effect of fluid inertia on the force response of Squeeze Film Dampers (SFD) is a subject of great importance since most existent damper applications operate with Reynolds numbers in the range of one to ten. For small ...
Probabilistic analysis of foundation forces for a class of unbalanced rotating machines
(1980)
This dissertation considers the problem of the foundation force of an unbalanced rotating machine from both deterministic and probabilistic viewpoints. The rotor-housing is modeled as a three degree-of-freedom system wherein ...
Improved analysis of laminated heterogeneous beams and associated formulation of a new finite element method
(1988)
Kirchhoff's theory for plates and Bernouilli-Euler's theory for beams ignore the effects of transverse shear and normal deformations on stresses and displacements. Various subsequent theories have incorporated these effects ...
Measurements and uses of elastic constants for determining the technical constants and Debye temperature
(1988)
This dissertation deals with the subject of testing the methodology of the PUCOT (Piezoelectric Ultrasonic Composite Oscillator Technique) for measuring the elastic constants, providing an improved method of using sound ...
Determination of the mode I delamination fracture toughness of multidirectional composite laminates
(1988)
The objective of this study is to develop and verify a theoretically-based method for characterizing mode I delamination fracture of composite laminates. Attention focuses on the special problems associated with delamination ...
The prediction and measurement of incompressible flow in a labyrinth seal
(1986)
A computational/experimental study was conducted on the incompressible flow in a labyrinth seal at a variety of leakage rates and seal rotation rates. The predictions were obtained using a finite difference code that ...
An optimal gain adaptive control system for CNC metal cutting machine tools
(1986)
The optimal gain adaptive control system described in this dissertation is a nonlinear, sampled data system which is designed to regulate the cutting force during turning operations. The controller is designed to keep the ...
