ENERGY IN THE AGE OF CLIMATE CHANGE - Italy Joins European Nuclear Power Revival
Speaking of Grand Challenges, why we never talk of Energy in Imechanica? There are certainly mechanical implications. And Energy is top of the list at the www.engineeringchallenges.org project.

Italy Joins European Nuclear Power Revival
The Future of Meshless Methods
I joined imechanica almost a year ago and I've been frequently following its interesting discussions, even the most animated ones. I think that a place like this is ideal to foster the exchange of ideas in the scientific community;
Moreover it is fantastic as a simple student like me can interact and easily ask questions to the most important researcher in the field of mechanics.
Time dependent vs Independent
In Computational mechanics, for rate(time) dependent calculations (eg. Creep, plasticity), when we say time step dt, does it mean physical time.
Can I think this way:
I start at time 0 and calculate stress, strain etc after 1 sec, 2 sec, 3 sec..
Also, what exactly is strain rate? why do some books say ..'when a strain rate is applied'''..I'm confused..dont we just apply displacement or force all the time.
Sia Nemat-Nasser Early Career Medal Established
Spring 2008: The Materials Division of ASME is pleased to announce the creation of The Sia Nemat-Nasser Early Career Medal in honor of Dr. Sia Nemat- Nasser, Director of the Center of Excellence for Advanced Materials at UC San Diego and Distinguished Professor of Mechanics and Materials. This award is given to recognize research excellence in the areas of experimental, computational, and theoretical mechanics and materials by young investigators who are within 10 years after their Ph.D. degree, with special emphasis placed on under-represented minorities and women.
Modeling of cohesive zone model (CZM) using MSC.Marc
Hello everybody,
I am a new comer here and I need some help. I want to simulate the interface debonding process of bimaterial using the commercial FE software msc.marc, but I want to use my own cohesive law not the one given by the marc. so the user subrotine UCOHESIVE must be used, the problem is I dont know how to program using FORTRAN. I hope some one here can help me, if you have such a user subrotine, can you kindly sent it to me? that will give me a great hand. Thank you very much. Expect your reply.
Lecture 'Mechanics of Soft Active Materials' by Zhigang Suo was successfully held in Tongji Univ.
On May 29th, Prof. Zhigang Suo, a member of the US National Academy of Engineering and professor of Mechanics and Materials at Harvard University, made two lectures for teachers and students in Tongji University, titled “from study in Harvard to be elected to the US National Academy of Engineering” and “Mechanics of Soft Active Materials”.
Newsletter for the ASME Committee on Constitutive Equations - Summer 2008
Mechanics community,
Please find attached the summer 2008 edition of the ASME Committee on Constitutive Equations Newsletter. Included in the newletter is an article written by Prof. Ostoja-Starzewski on "Homogenization and Size of Representative Volume Element (RVE)".
Thanks,

Accounting for the overhang (or under etch) in MEMS resonantor structures
Hi,
I am wondering if there is a simple way to account for the overhang (or the under etch) in cantilever resonator structures when we are estimating for the resonant frequency of the same. It will be a great help.
Thanks,
Vivek Adiga
