Continuum mechanics, Micromechanics and Nanomechanics

Submitted by Jayadeep U. B. on Tue, 06/02/2009 - 05:03

Hi all,

Can anyone explain me the characteristic features of continuum mechanics, micromechanics and nanomechanics? My present level of understanding is:

A Ph.D. Research Assistantship position in multi-scale computational mechanics of fracture of composites (with application on concrete) will be available to start in January 2010 in the Department of Civil Engineering, at the University of Colorado at Boulder, Colorado, USA.

Calculation of potential energy in conditions of prescribed displacement and prescribed loading

fracture mechanics; J-intergral

A question has arised when I read a book about fracture mechanics recently.

This question is about the calculation of potential energy in "fixed-grips" (prescribed displacement) and "dead-load" (prescribed displacement).

Thermal stresses

Hi,

I am having confusions about the concepts of thermal stresses of an un-constrained elastic body when heated/cooled.

Let's say if I have an elastic body of an arbitrary geometry. If I subject it to a uniform temperature change without any constraints, then there will no thermal stresses at the end of the analysis. I guess I am right till here.

I'm a MSc (Applied Math) student modelling vibrating bridge hanger cables using corotational method. I'm interested in chatting with anyone using this method, especially for cables/beams but also other contexts. Thanks, John.

Elastic-Perfectly Plastic in Abaqus Explicit

Plasticity

Dear Mechanical Engineers,

It's my pleasure to be one of your group. I have a question in Abaqus Explicit and all my friends recommended me to as iMechanica as the explicit Abaqus is more popular to you than us as civil engineers.
