The number of registered users of iMechanica passed 16,000 early today.  The the number of posts passed 6,900, and that of comments, 12,500. 

iMechanica was founded in September, 2006, with the mission:

1. to use the Internet to enhance communication among mechanicians
2. to pave a way to evolve online all knowledge of mechanics

I quote what I wrote when the number of registered user passed 1000 in early 2007:

Professor Huajian Gao, Brown University, will give the Robert Henry Thurston Lecture at the 2009 International Mechanical Engineering Congress, Orlando, Florida.  His lecture “Nanomechanics of biological systems - What can we learn from nature about hierarchical materials?” will be in room Euro 10, on the 3^rd floor at the Walt Disney Dolphin Hotel (conference hotel), at 10am, November 16, Monday.

A postdoctoral position is available in the area of multiscale modeling of granular solids. The position is supported by the National Science Foundation and industrial partners of the NSF Engineering
Research Center for Structured Organic Particulate Systems (http://ercforsops.org/). 

The part of full field displacement measurements is increasing in
experimental mechanics. Their taking into account relies on the
development of suited identification approaches, which have to be able
to take advantage of their richness. When dealing with composites, they
offer the possibility to perform the identification at a scale where
the material is heterogenenous. The goal of this thesis is to apply
inverse approaches on the challenging case of the identification of
heterogeneous elasticity and develop a robust identification

A thin film subject to compressive strain can either bend (for large strain gradient) or wrinkle (for small strain gradient). The bending is traditionally used in thermostats (bimetal stripes), but couple of years ago, it was extended to the nanoscale thin films which can bend and roll-up to tubes with defined number of rotations. The wrinkles are also rather common in macro- and microscale thin films.
Here, we developed an equilibrium phase diagram for the shape of
compressively strained free-hanging films by total strain energy
minimization.

Hi all,

If you can pls advise me to modelthis experiment.

First I have applied a constantload for the steel member.

Then I have increased thetemperature of one of the member surface with time

until the member got failed.

This resulted in non-uniformtemperature variation across the section.

I have measured the temperaturesof the different surfaces of the member and

I would like to use thesetemperature values in my structural modelling.

Now I would like to model themember so that I can find out the time

What are the effects of magnetism on stresses while material is under loading condition?Is there any relationship between magnetism and stress?

Thanks!

Hei,

 I am a new learner of XFEM. I want to start some exmaples in ABAQUS. The tutorial in ABAQUS is rather crude. If any body has experience, May I have small notes on how to solve problems with XFEM in ABAQUS?

Thank you for your help.
