Clarifications o Stroh formalism

Submitted by Ramesh Babu.Manda on

sir,

I am solving some problomes for Stresses around holes for Anisotropic cases. In this connection most of authors have solved the stresses in cartesian co-ordinates only. Can I have any papers which are solved in polar co-ordinates by Stroh formalism for Stresses around holes in Composite laminates.So kindly help me

thanking you

von Karman plate equations

Submitted by Rui Huang on

Many of us (including myself) have used the nonlinear equations for elastic plates, originally proposed by von Karman (1910). I recently came across a book with some interesting comments about the plate equations, which may be of interest to share with others on imechanica. The book's title is "Plates and Junctions in Elastic Multi-Structures", authored by Philippe G. Ciarlet and published by Springer-Verlag in 1990.

Looking for a postdoctoral position in materials science and engineering

Submitted by 329878819@qq.com on

Dear all

I am looking for a postdoctoral postion/research fellow in materials science and engineering. My background and skills in lab techniques will prove to be an effective match for your qualification.

I have a master' degree in materials science and engineering and will get my PhD degree of materials science and engineering at the end of 2010' spring. I have been focused on the field of TiAl-based alloy, with particular attention on smeling and casting, phase transformation, numerical simulation of flow field using ANSYS for four years.

how to start a research

Submitted by mbmohan on

hi all,

 I am a mechanical engineer currently pursuing Master degree (Post graduation). Ultimately i also want to pursue a research leading to PhD after my master's. Its my burning desire to do some significant research in the field of Fatigue analysis using Fracture mechanics approach preferably for aerospace domain using advanced CAE softwares like Nasgrow, Afgrow, Abaqus, FE-safe, MSC Fatigue, etc,..

I'm looking for a new vibration exciter

Submitted by haitao hu on

I'm looking for a new vibration exciter which exciting frequency can reach 300hz .I'll use it to load the cantilever beam specimen , compare the  fatigue life of the specimen under different loading frequency. the electric exciter can not  generate the same amplitude under difference exciting frequency.

who can tell me that how can I found or design a mechine to finish the expriment.thank you

Compositional patterning in coherent and dislocated alloy nanocrystals

Submitted by vh on
Variations in the distribution of the alloy components can significantly influence the electronic properties
of self-organized alloy nanocrystals. Using a combination of finite element and quadratic programming
optimization methods, we have developed an efficient numerical technique to compute the equilibrium
composition profiles in coherent and dislocated nanocrystals. We show that the variations in composition
profiles arise due to the competition between chemical mixing effects and the relaxation of composition-
dependent mismatch strain as well as strain due to dislocations. We find that the composition profiles

Drupal, the software that powers iMechanica, treats comments very differently from a blog entry.  You cannot attach a file to a comment directly. 

One way to link to a file in the comment is to first write a new blog entry, where you can upload the file. The blog entry and the uploaded file have distinct URLs. In your comment, you can choose to hyperlink to your blog entry, or to the uploaded file.
