Post-doctoral Research Associate Position

Submitted by Teng Li on Tue, 10/13/2009 - 11:39

job

A post-doctoral research associate position is available immediately in the Department of Mechanical Engineering, and Maryland NanoCenter at the University of Maryland, College Park, in the area of multi-scale modeling (from atomistic, molecular, coarse-grained to continuum) of carbon-based nanostructured materials. Material properties of specific interest include mechanical and electrical properties, with special focus on deformation/failure mechanisms and bandgap engineering.

Pijaudier-Cabot and Bazant concept of non local damage

Submitted by ss09 on Mon, 10/12/2009 - 12:03

research

Hello all,

I would like to seek help on a topic on which I am slightly ignorant.

I do not understand the concept of non local damage and the internal length of the non local continuum as described by the well quoted paper of Pijaudier-Cabot and Bazant (1987) in continuum damage mechanics. So may I please ask the experts in this forum to please explain to me using some simple analogy.

Dependence of relaxation time on the polymer length (via a string of viscoelastic springs)

polymer relaxation time

Dear all,

According to polymer theory, the relaxation time depends on its length (or unit number), and there exist some relationships to describe such dependence. The smaller number of polymer units, the smaller the relaxation time of the polymer is. How to describe this via a simple model of visco-elastic springs?

Chatyter Vibration Mechanics

Can anyone cite some resources for chatter vibrations...the google search results dont throw up good results...I need some thing that will explain the basics - mechanics,causes, measuring and control of chatter in machine tools!
