Unsolicited proposals on Dynamical Systems

Submitted by Ken P. Chong on

The Dynamical Systems program in the Directorate of Engineering and the Applied Mathematics Program in the directorate of Mathematical and Physical Sciences Sciences, of the National Science Foundation, have just published a joint "Dear Colleague Letter", expressing interest in special topics in Dynamical Systems.  The letter encourages unsolicited proposals on the following topics:

Pressure vessel: ASME section VIII division II

Submitted by jiang62 on

Hi, everyone,

I am wondering whether anybody could explain how to determine primary stress and secondary stress when FE software is used when the pressure vessel is designed using ASME section VIII vision 2.

The code has some explanation using plasticity (self-limiting). But it is very hard to use for practical use.

Thanks

Exact relations in the micromechanics of composites

Submitted by Biswajit Banerjee on

There are several exact relations from the theory of composites that can be used to determine whether a new numerical or analytical approach gives reasonable answers. Here's a paper on some exact relations that I wrote up a long time ago and just recently posted on Scribd. 

The post LHC universe?

Submitted by Biswajit Banerjee on

Most of you have heard about the commissioning of the Large Hadron Colider (LHC) by CERN and then the explosion of Helium followed by a postponement of operation until spring next year.  One of the worries some people had was that a mini black hole would be created by the collsions.  Also, the anthropic principle in one of its forms suggests that every possible universe exists but we see only our universe because it's the one in which intelligent observers exist.

Simple and highly accurate two dimensional finite elements for laminated composite structures

Submitted by psubbu2000 on

I have developed a set of simple and highly accurate two dimensional finite elements for the analysis of laminated composite structures. These elements are capable of accurately predicting three dimensional stress state (all six stresses) using constitutive law.  These elements reduce modeling effort, computational time and increase solution accuracy.

Can someone suggest me a proper source to support my research financially?
