Mechanical Constraints Enhance Electrical Energy Densities of Soft Dielectrics

Lin Zhang, Qiming Wang and Xuanhe Zhao*

 Applied Physics Letter, In press 

Abstract

            Dielectrics are essential components in modern electronics and electric systems. When a sufficiently high voltage is applied on a layer of a dielectric, the dielectric will breakdown electrically. The breakdown limits the electrical energy density of the dielectric. We show that constraining the deformation of soft dielectrics can greatly enhance their breakdown electric fields and thus increase their electrical energy densities.

Hello, 

We start a three-year program for academician researchers, PhDs and etc. We suppose that our multiobjective IOSO optimization technology may help you in your research and investigations. 

What we offer for you:

I am a final year Master of Engineering student at Materials Engineering Department, Indian Institute of Science. I have done my Bachelor of Engineering in Mechanical Engg. from Bengal Engineering and Science University, West Bengal, India. Currently I am working on my ME project "Simulation and Validation of Roll-Separating force and Limiting Reduction in Cold Rolling", under Prof Vikram Jayaram, Materials Engg Dept. and Prof S.K.Biswas, Mechanical Engg. Dept, IISc., Bangalore. After completion (June, 2011) of my ME, I want to do Phd. in the field of Computational Solid Mechanics, Fracture Mechanics and Materials Engineering. I am looking for a Phd. position in these fields. 

Please find my CV as an attachment.

Hi,

I'm looking for a faculty, post doctoral, or research position in the United States.

Thanks to Marino, I have found the reason for the difference in our bending stiffness calculation. The original discussion is here:
http://imechanica.org/node/4029

The reason why we have a higher bending stiffness is due to the dihedral term. This dihedral term does have a significant contribution to the bending stiffness. However, in Ref. [26], apparently, this dihedral term was ignored.
I have written a short document showing the contribution of the dihedral term to the bending stiffness. Please take a look at the attachment.
I received great help from Dr. Huang and Marino. Thank you very much.

Hello everybody

     Thanks for your loads of response and I am glad that you have given such valuable data regarding MDBT.

M ostly I need some more data reagarding MDBT and its fixture design.What should be the exact design procedure to perform this test and what should be the exact circumstances and precautions need to be taken are the concerned area where I need your help.
Its hearty request to help me sort out my problem and let me help in this regard.

you can send emails, links,images on my email ID too. My email ID -bapu285@gmail.com.

You can even send me the data directly on this blog.

waiting for response from you all .

Giving presentations at conferences or seminar series is a vital part of a researcher's professional life.  Listening to others' presentations is also one of the best ways to stay current with the frontier of a research field. While the audience in conference/seminar room is often limited, a presentation posted online can be virtually viewed by any interested audience. At iMechanica, users have started to post their presentation slides, quite often as the attachments of a post briefing the presentation.  Such a way is simple and effective, but may not be the best way for everyone for the following reasons:

From the blogosphere

Nature 453, x (2008). doi:10.1038/7196xc

Does a scientist who has had three patents in the past five years,
but only three papers, each cited just three times, deserve more
recognition than one with five Nature papers and 1,000 citations? 

Can anyone download the full paper I have no access to Nature!!!! 

Dear Imechanica friends

  I recently pointed to a very interesting paper by Fabio Casati and collegues from Trento University in Italy.

They say PUBLISH AND PERISH: WHY THE CURRENT PUBLICATIONAND REVIEW MODEL IS
KILLING RESEARCH AND WASTING YOUR MONEY

as opposed to the current mania to PUBLISH and killing yourself with writing papers.

Arash, I am quite shocked by your reply http://imechanica.org/node/3045#comment-7151.  First you say "with all the due respect", then you say "trivial history".  But you prudently say "maybe I miss the point".  Maybe useful to clarify, also because probably iMechanica should start a discussion about history of mechanics starting a little earlier than this century. How can we judge Leonardo da Vinci? He has no published papers, no citation, no index, no Nobel prize... Not even a Timoshenko medal!  Maybe we should give him one post-mortem?    Please see the attachment.  Watch also the videos:

Lately I have been thinking that "Graduate Student" is a misnomer. The correct title should be "Graduate Research Assistant" or "Graduate Engineer".  After more than a year spent in industry, I think that there really is no difference in the work done. Except that the work environment is more flexible in academia.

When I came to the institute, my collaborator Kay invited me for a dinner in the new town together with his friend Thilo and other guys. The city is wisely divided into two functioning areas, old town and new town. All the ancient buildings like King’s summer palace, women’s church and opera house are in the old town; while the restaurants, bars and other modern buildings are in the new town. Each is in harmony with its environment and cultural atmosphere.

Helloooooo Friendz

 I need your help

I have to submit a research proposal and the topic is:

Foreign Trade is the key catalyst for the economic development of Pakistan

Kindly help me as soon as possible.....

Thanks

 The Koiter-Sanders-Budiansky bending strain measure and a nonlinear generalization

 We know from strength of materials that non-uniform stretching of fibers along the cross section of a beam produces bending moments. But does this situation necessarily correspond to a 'bending' deformation? For that matter, what do we exactly mean kinematically when we talk about a bending deformation?

To make the question more concrete, consider a cylinder that expands uniformly along all radial rays. Does this deformation of the cylinder correspond to bending? I think it is fair to say that most would say that this is purely a stretching deformation with no bending. But then, what is precisely a bending deformation?

Please see the attachment

I guess, it is an example of as apersonal and unspirited a paper as can at all be produced.
