Numerical and experimental stress analysis of a polymeric composite hip joint prosthesis
(John Wiley & Sons Inc, 1996)
A comparative stress analysis of a polymeric composite hip joint replacement was performed. A prototype short carbon-fiber reinforced PEEK (CF/PEEK) prosthesis was manufactured by injection molding. Finite element (FE) ...
Application of the dynamic stiffness technique to the in-plane vibrations of plate structures
(Pergamon-Elsevier Science Ltd, 1996)
In this study the dynamic stiffness technique, which yields ''exact'' results for a certain class of plate structure, is extended to include in-plane vibrations. Using the equations of motion and edge tractions the stiffness ...
Motion estimation using common spatial frequencies in synthetic aperture imaging
(I E E E, 1996)
Correlation processing using fully common spatial frequencies of overlapping subapertures is explored for motion estimation between consecutive excitations in multi-element synthetic aperure imaging. Signals derived from ...
Beam space processing for low-cost scanners
(I E E E, 1996)
A subaperture processing technique suitable for low-cost ultrasound imaging systems is presented. The technique is based on multi-element synthetic aperture approach and beam interpolation. A large receive aperture is ...
An assessment of the effects of in-plane vibrations on the energy flow between coupled plates
(Academic Press Ltd, 1996)
The majority of the studies of energy transmission in plate-type structures are based on the assumption that the main component of the energy transfer is due to flexural waves, and the contribution of in-plane waves may ...
Natural frequencies of cross-ply laminated singly curved panels

A cost-effective method for ultrasound volumetric imaging
(1996)
A synthetic receive aperture technique is explored for cost-effective ultrasound scanners with high frame rates and beam density. The technique provides ultrasound volumetric imaging where beam count is very large with 2-D ...
