The Cosmic Origins Spectrograph (COS) was installed in the Hubble Space Telescope in May, 2009 as part of Servicing Mission 4 to provide high sensitivity, medium and low resolution spectroscopy at far- and near-ultraviolet wavelengths (FUV, NUV). COS

Bodner-Partom Constitutive Model and Nonlinear Finite Element Analysis
Autor: F. A. Kolkailah, A. J. McPhate
Publikováno v: Journal of Engineering Materials and Technology. 112:287-291
In this paper, results from an elastic-plastic finite-element model incorporating the Bodner-Partom model of nonlinear time-dependent material behavior are presented. The parameters in the constitutive model are computed from a leastsquare fit to exp

A Semi-Analytical Investigation of Fatigue Stresses in a Bolted Headplate by Finite Elements and Classical Plate Theory
Autor: G. Steven Gipson, J. C. Ortiz, A. J. McPhate
Publikováno v: Journal of Vibration and Acoustics. 109:302-308
A semi-analytical analysis involving finite elements in conjunction with classical plate theory is used to determine the stress state in a concentrated region of the headplate on an industrial ball mill. The study illustrates the practical benefits o

Computation of structural error for nonlinear band mechanisms
Autor: Andrew J. McPhate, Larry J. Havard
Publikováno v: Mechanism and Machine Theory. 10:337-346
This paper presents an algorithm for computing the structural error imposed on the design of band mechanisms by contour imperfections. These mechanisms are very accurate theoretically over their entire range of operation; however, in practice, innate

Function generation with band mechanisms
Autor: Andrew J. McPhate
Publikováno v: Journal of Mechanisms. 1:85-94
The design equations for band mechanisms closely resemble the design equations for cams, and as such they are solvable for a broad class of functional constraint. However, band mechanisms have more severe physical compatibility requirements than cams
