Postprocessing effect on the ductility and flexural behavior of three titanium alloys under simulated superplastic forming conditions
Journal of Materials Engineering and Performance, 2004Co-Authors: F. Pitt, M. Ramulu, P. Labossiere, S. YoungAbstract:Ductility of three titanium alloys was evaluated after exposure to time and temperature conditions representative of superplastic forming (SPF). Following exposure, flexural specimens were postprocessed to remove the α-case by one of three methods: no material removed, the standard amount of material removed by chemical processing, or a reduced amount of material removed also by chemical processing. Results include the evaluation of the specimens per ASTM E 290-97a and AMS-T 9046, springback analysis, and prediction of Minimum Bend Radius criteria for the three alloys from finite element method simulation. It was found that results varied based on alloy and exposure temperature and the reduced postprocessing of titanium SPF parts produced acceptable results under certain conditions.

FINITE ELEMENT ANALYSIS AND EXPERIMENTAL VERIFICATION OF SOI WAVEGUIDE LOSSES
2011Co-Authors: H. SrinivasanAbstract:of Thesis FINITE ELEMENT ANALYSIS AND EXPERIMENTAL VERIFICATION OF SOI WAVEGUIDE LOSSES Bending loss in silicon-on-insulator rib waveguides was calculated using conformal mapping of the curved waveguide to an equivalent straight waveguide. Finite-element analysis with perfectly matched layer boundaries was used to solve the vector wave equation. Transmission loss was experimentally measured as a function of Bend Radius for several SOI waveguides. Good agreement was found between simulated and measured losses, and this technique was confirmed as a good predictor for loss and for Minimum Bend Radius for efficient design.

Finite element analysis and experimental verification of SOI waveguide Bending loss
Microwave and Optical Technology Letters, 2009Co-Authors: H. Srinivasan, B. Bommalakunta, A. Chamberlain, Jeffrey Todd HastingsAbstract:Bending and transition losses in silicon-on-insulator rib waveguides were calculated using finite-element analysis of equivalent straight waveguides with perfectly matched boundary layers. Experimental loss measurements of silicon-on-insulator waveguides with various Bend radii reveal that this technique accurately predicts loss and Minimum Bend Radius for efficient design. © 2009 Wiley Periodicals, Inc.
