Thin-Film Elastic-Property Measurements With Laser-Ultrasonic SAW Spectrometry

November 1, 2001
Author(s)
Donna C. Hurley, Vinod K. Tewary, A J. Richards
We have developed laser-ultrasonic methods to evaluate the elastic properties of thin films. Our method, called SAW spectrometry, used broadband surface acoustic waves (SAWs) generated by a line-focused, pulsed laser, SAWs with frequency components up to

Greens Functions for Boundary Element Analysis of Anisotropic Bimaterials

May 1, 2001
Author(s)
J R. Berger, Vinod K. Tewary
We present several region-dependent Green's functions for anisotropic bimaterials in two-dimensional elasticity and steady-state heat transfer problems. The details of the various Green's functions for perfect, slipping, and cracked interfaces are given

Green's Function for Steady-State Heat Conduction in a Bimaterial Composite Solid

June 1, 2000
Author(s)
J R. Berger, J L. Skilowitz, Vinod K. Tewary
The derivation of a Green's function for steady-state heat conduction in anisotropic bimaterials is presented. The Green's function is obtained through a Fourier representation to obtain both free-space, singular parts and region-dependent, regular parts

Lattice-Statics Model for Edge Dislocations in Crystals

June 1, 2000
Author(s)
Vinod K. Tewary
A lattice statics Green's function method is described for modeling an edge dislocation in a crystal lattice. The edge dislocation is created by intoducing a half plane of vacancies as in Volterra's condtruction. The defect space is decomposed into a part
