I am working on wave propgation in solid and interested in ultrasonic field modeling in different types of planar and non-planar structure.Is anybody familiar with any method (like FEM, BEM) which has been used to show that if a bounded beam strikes a solid surface with critical angle then a clear field of surface wave can be seen. That is no beam is passing inside the solid body for critical angle and if the angle is incresed then total reflection can be seen. Also is there any literature where the total ultrasonic field(contour plot) is shown for different inclination angle of transducer?
I work in gas turbine business and I noticed following phenomena so I would like someone helps me to understand.
I noticed that component made as full ring remains circular after load with outer pressure and temperature gradient (Figure 1) and component made as connection of 2 halfrings (Figure 2) deforms as on Figure 3.
I find, as major cause of such deformation, temperature gradient which affects as on Figure 4, but replacing connection with outer momentum I can (using integrity laws - I am not very familiar with Elasticity theory) receive only circular shape, because same momentum in section results with same local radius of curvation as on Figure 5.
The Robert M. and Mary Haythornthwaite Foundation is offering $1,000 travel grants for U.S. graduate students currently enrolled at any U.S. universities or colleges presenting a paper in any field of applied mechanics at the 2007 International Mechanical Engineering Congress and Exhibition (IMECE) in Seattle, Washington, November 11 – 15, 2007.
We professors usually start our jobs unprepared. In our days as students, we are considered talented if we can solve problems posed by our professors. We might be even considered brilliant if we can solve them quickly and make a few extensions. After solving a few such problems, we write a thesis. We are then entrusted with a job as a professor. We soon realize that the skill of solving problems posed by others only plays a minor role in our jobs. We have to pose new problems, persuade our peers that our problems are worth solving so that someone will fund us, and motivate students to solve them. Each of the three aspects demands a distinct set of skills. On top of these, we have to teach classes and serve on committees. Our days as students do not prepare us for our jobs; we must learn on the jobs. Perhaps there is nothing unusual about this lack of preparation in any profession. Let us just hope that our doctors are better prepared before they learn something while treating us.
Perhaps we can help each other to learn to be professors by recounting our experience. This thought came to me this morning, and I'm writing to tell you about a recent experience of mine.
Recently I saw an animation
named “The inner life of the cell”, which was made by Howard Hughes Medical Institute and Harvard University Biovision. It can be watched online only:
I need some introductory materials to be familiar with soft tissues in biomechanics. Is there anyone who can help me?
Dear Fellow Mechanicians,
I wanted to call you attention to the technical committee meeting schedule (AMD committees are listed under "A") for the upcoming IMECE meeting in Seattle, and in particular to mention that the Fracture and Failure Mechanics Technical Committee (FFMTC) meeting will take place Tuesday, November 13th from 3:00-4:00. The location should be listed in the final progam. The FFMTC is an open membership committee, so if you are interested in being involved, please attend the meeting.
The 5th European Conference
on Complex System is holding in Dresden, Germany now. This is really
an emerging research area. The multiple para-sessions themselves show
how diverse and multi-disciplined it is. It includes:

An updated Call for Nominations for the awards administered by the Applied Mechanics Division has been posted on the AMD website. Please nominate worthy candidates to these awards.
A new award, named the Thomas K. Caughey Dynamics Award will be awarded for the first time in 2008. In addition, the Applied Mechanics Division Award and the Young Investigator Award have been endowed by the friends of Ted Belytschko and Thomas J.R. Hughes respectively.
The Department of Mechanical Engineering seeks an outstanding
individual at the rank of Assistant Professor or Associate Professor
without tenure, in the area of Computational Mechanics.
I am pleased to announce that Volume 1, Number 1 (January 2008) of the Journal of the Mechanical Behavior of Biomedical Materials is published in both print and online on ScienceDirect. This first issue contains three excellent review articles on bone and dentin, human enamel, and biocompatability of Ti-alloys as well as eight research papers.
The online version of all four issues in Volume 1 can be viewed free of charge until September 2008. For further details please see http://mail.elsevier-alerts.com/go.asp?/bESJ001/mQNA874/uOPDV5/xS5EBB

A technique for setting up generalized continuum theories based on a balance law and nonlocal thermodynamics is suggested. The methodology does not require the introduction of gradients of the internal variable in the free energy. Elements of a generalized damage model with porosity as the internal variable are developed as an example.
A field theory of dislocation mechanics and plasticity is illustrated through new results at the nano, meso, and macro scales. Specifically, dislocation nucleation, the occurrence of wave-type response in quasi-static plasticity, and a jump condition at material interfaces and its implications for analysis of deformation localization are discussed.
While I have been traveling, writing papers, and submitting proposals for the last few months, I have not been keeping up with readings. Just notice today an old news: News York Times has just made even more content free online. For example, without subscription you can read columns of Tom Friedman, the author of The World is Flat. You can make links to them to share with other people. For example, his column today is titled 9/11 Is Over.
I just remembered another video that I had seen some time ago. Many of you have probably seen it but here it is for those who have not. (The original page where I found it is http://www.maniacworld.com/Laminar-Reverse-Flow.html.)
Prof. Pat McMurtry's explanation is:
The governor of Virginia has asked President Bush to award the Presidential Medal of Freedom posthumously to Professor Liviu Librescu, a Holocaust survivor who died trying to save his students during the mass killings at Virginia Tech. Read more.
You may want to know about a petition to ask George Bush to grant Liviu Librescu the Presidential Medal of Freedom. Please consider signing it, and tell others about it.

The one-million-dollar Kavli Prizes in Nanoscience, Neuroscience and Astrophysics call for nominationsSubmitted by Zhiliang Zhang on Sat, 2007-09-29 04:40.
The Kavli Prize – three international awards for outstanding contributions to the fields of nanoscience, neuroscience and astrophysics – will be awarded for the first time in 2008. The Kavli Foundation has established these international awards to recognize seminal advances in scientific research. Each prize will consist of a scroll, a medal and a cash award of USD 1 million.
The Prizes will be awarded at a ceremony in Oslo, Norway, Fred Kavli’s native country, every two years, beginning in 2008. http://www.kavliprize.no/
When a strained film is grown on a vicinal substrate, the steps advance like a train when the deposited atoms have sufficient mobility to reach the step edges. However, as the steps advance, the strain-induced force monopoles associated with the steps cause the steps to attract to each other (J. Tersoff, PRL 74, 4962, (1995)), resulting in a thermodynamic instability of the steps in the form of step bunching (J. Tersoff, et al., PRL 75, 2730 (1995)).
The following video is a nice depiction of how the eigenmodes of a plate change with increasing forcing frequency.
The 20th Annual Melosh Competition for the Best Student Paper on Finite Element Analysis will be held at Duke University on April 25, 2008. The competition has become one of the premier graduate student events in the broad area of mechanics. We have held the competition at a variety of locations over the past several years, and this year we are returning to Durham.
