iMechanica

Hi all,

It is very good to see postdoc jobs posted in imechanica .I want to apply for postdoc position in solid mechanics ,however, i have never written a postdoc research proposal.I dont know how it is different from statement of purpose that is required for a graduate research. 

I tried but could not find any sample postdoc research proposal on internet.

I would greatly help if anyone can send me his/her actual or sample postdoc research proposal 

Thanks and Regards,

Sonia Chopra 

Subject to a voltage, a dielectric elastomer can deform substantially, making it a desirable material for actuators. Designing such an actuator, however, has been challenging due to nonlinear equations of state, as well as multiple modes of failure, parameters of design, and measures of performance. This paper explores these issues, using a spring-roll actuator as an example.

A Post-Doc Position is avalaible in Bio-Mimetic Adhesive Interfaces (EbioAdI) at the University of Mons-Hanaut, Belgium

Supervisor: Prof. Pascal Damman, PhD
University of Mons-Hainaut
Interfaces & Complex Fluids Lab (InFluX)
European Collaborative Research Project (ESF-Eurocores)
Duration : 1 – 3 years
Deadline: 1 September 20088

In short:

Plans are underway to issue a solicitation for the Science and Technology Centers Program in July 2008. Please visit the STC website for updates: http://www.nsf.gov/od/oia/programs/stc/index.jsp

How to develope a new potential function.

For instance, if I want to study a new material system by classical MD, for which the existing potential force fields are not suitable.

I would like to know the standard procedure, how to use the first principle studies/ experimental data and how to select the basic functions...from the experts in this area.

I am trying to apply Berendsen thermostat for CNT. When I choose to leave one third of the tube atoms to evolve freely with out distrubing the momentum, I am unable to acheive the target temperature and further temperature increases gradually over the whole simulation run (even with a thermostat parameter equals to the timestep i.e., like a simple scaling). How it is possible to acheive target temperature,by scaling only a part of atoms, using some scaling value which should actually scales all the atoms momenta.

Attached is a tar archive for a Fortran 90 library to compute maximum-entropy basis functions.  I have used the G95 compiler. The manual in PDF is also attached and a html version of the same is also available, which provide details on how to install the code and its capabilities.

One of the most important things every researcher does in the beginning of his introduction to a topic is review process. Most helpful papers in this regard are review papers. Review papers are important. They are primary and best way to understand the value of a work for the societyto award and grant. They help researchers to find out needs of people who use our research and goal functions of scientific society. Help researchers to find out good topics and also good solutions. And the final effect of a research on the society.

I've started to look into the modeling of polyurethane.  So far I'v found one paper that specifically looks into how to model the mechanical behavior of PU. It describes a possible constitutive model for PU:

Stress-strain behavior of thermoplastic polyurethanes, Qi,H.J.; Boyce, M.C., Mech. Mater. 2005, 37, 8, 817-839

Does someone know of any other resources on the modeling of PU?  Thanks, Andreas

Consider a ridig pillar ontop of a elastic substrate. Applying a moment to the pillar will lead to elastic deformation of the substrate. If the pillar is infinitly large in diameter, then this problem is the same as an infinitely sharp crack, considering the symmetry of the crack problem, i.e. there are square root singularities. However, the infinitly large diameter assumtion does not hold if the global rotation of the substrate under the pillar is of interest, because the both sides of the pillar interact.

dear imechanica friends

   the Grand challenges  for Engineering make clear that we should work for the good of our Society.  So, how much of technology really makes are happier?

hi all

i want to make a model of  e-glass epoxy composite laminate with [45(10),0(10)] of 20 layers with out considering the symmetry

i have fundamental knowledge about ansys

please  suggest the procedure

I am a junior graduate student now, and very interesting in wave motion. My advisor Prof. Zhong wanxie and his PHD student qiang Gao have developed a precise numerical technique to solve the Rayleigh wave frequency equation, which can avoid the missing root. They did a systematic work involving surface wave propagation in a transversely isotropic stratified solid resting on an elastic semi-infinte space, wave propagation in the anisotropic layered media and the propagation of stationary and non-stationary random waves in a viscoelastic, transversely isotropic and stratified half space.

Info:  The goal of this project is to investigate the mechanical and acoustical behavior of materials characterized by a well-defined miscrostructure. The research will involve experimental, theoretical and computational mechanics.

We are looking for an enthusiastic, science-driven, outstanding young
candidate with experience in solid and structural mechanics. Experience
with basic mechanical testing techniques is also appreciated.

Teacher, Scientist, or Engineer

From thinking about the 'I'd Love to Change the World' discussion, I have concluded that my dilemma stems from the (basically) three career paths from which I can choose.

A teacher that can have a great deal of influence on a select number of other individuals' lives and can take great pride in helping others achieve their potential, and possibly make great contributions to society.

A scientist that can continue to explore the unexplained and hopefully discover something that could contribute to society.
