New Book "Tissue Mechanics"

Submitted by MichelleLOyen on

A new book, "Tissue Mechanics" by SC Cowin and SB Doty is of potential interest to those from a classical mechanics background considering work in biomechanics. Downloadable versions of the first two chapters are available at the book's website along with a full table of contents and other supplemental information.

DEPARTMENT CHAIR: San Diego State University, Department of Mechanical Engineering

Submitted by Eugene A. Olevsky on

The Department of Mechanical Engineering invites applications and nominations for the position of Department Chairperson to begin in Fall 2007.

Applicants must hold an earned PhD in Mechanical Engineering or closely related discipline. A record of leadership showing interpersonal skills and organizational ability, strong research background and funding records with recognized professional accomplishments in mechanical engineering, demonstrated ability to interact with industry, and a commitment to excellence in teaching at both undergraduate and graduate levels are required. Mechanical Engineering is one of four departments in the College of Engineering at San Diego State University with an EAC, ABET-accredited B.S. degree program in Mechanical Engineering, as well as M.S. and Ph.D. programs involving students in leading edge research.

Heritage for Experimental Mechanicians

Submitted by Kyung-Suk Kim on

On July 16, 1976, when I was writing my very first paper in U.S. with my lab senior Dr. Prashant Kumar and thesis advisor Professor Rodney J. Clifton to the Journal of Applied Physics, Professor Clifton put a copy of an article on my desk while I was away. The article was "Advice to Young Physicists" by Walther Bothe. It was translated from German to English in Physics Today, September, 1958. I do not know whether this advice still holds for the whole; however, I believe that most of the advice is still valuable for anyone, in particular, an experimentalist, who undertakes a piece of scientific work. Therefore, I would like to share his advice with the society of iMechanica by recollecting it here. - K.-S. Kim

Nanostructure Transformation Based on Surface Science

Submitted by Hanchen Huang on

Much has been published about structure transformation of nanowires, nanorods, and nanoplates, under mechanical loading. Beyond hypes, the bottom line of these nanostructure tranformation is a simple piece of surface science - surface reconstruction and relaxation, which could be assisted by mechanical loading. Using ab initio calculations and analytical argument, we show such relationship for Z

Non linear cell mechanics

Submitted by Daniel Isabey on

Ex-vivo measure of stress-strain relationships in populations of living adherent cells by means of ligand-coated ferromagnetic microbeads (mean diameter: 4.5 µm) attached to the transmembrane mechanoreceptors which are linked to the cytoskeleton (CSK), reveal non linear cell mechanical behavior. However, this non linear cell mechanical behaviour is subjected to controversy for various reasons. First, it has not been systematically found. Results seem to depend on the micromanipulation method used and/or the cell type.
