Finite element modeling of transient ultrasonic waves in linear viscoelastic media

Abstract

This manuscnpt has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quali^ of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely afifect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included m the original manuscript have been reproduced xerographically in this copy, ffigher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge.

“…[25][26][27] There are two main models that can be used to solve the problem, a time-transient model and an alternative model based in the frequency domain. The timetransient model uses time-marching routines.…”
