CNT+polymer pulling out

Submitted by hamed_amini on

 

Dear all,



I am doing MD simulation of  pullout of CNT+polymer.

It is mentioned in some lectures that before pulling process the CNT should be
relaxed using potential like Brener and during pullout, CNT is considered as
rigid.

If the CNT is completely free to move during relaxation
it will be deformed and distorted and will stop the simulation.

For solving this problem I think that CNT should free to move only in axial
direction during CNT relaxation. Anybody have idea?


Help on Distribution of Bolt Load in 3D

Submitted by ruzbeh on

I am kind of new in computational simulation except for CFD. I have a cylinder which has a flange around it and a lid on top. Lid and the flange are connected by bolts and sealed with an o ring. Is it possible to simulate the load distribution around the flange due to tightening the bolts? Which package is most suitable for this comsol or Abaqus? I want to do simple simulation just to check whether the odd number of bolts are able to distribute load uniformly around the flange.

 

Thanks in advance.

looking for a PhD position

Submitted by anishiitk on

Dear all:

I am currently pursuing Master of Technology at Indian Institute of Technology,
Kanpur (India) in Mechanical Engineering department. In my masters thesis I am working on analytical and numerical (FE) analysis of dynamic buckling of thin walled circular cylindrical shells under fluctuating radial pressure. I am expecting to submit my thesis by the end of August, and after that I am planning for a PhD. I want to continue to work on the dynamic analysis of structure for my PhD thesis, and I am looking for a PhD position in some European or Canadian University.

impact damage due to laminar construction??

Submitted by setareh on

Hi everyone,

 

According to a book chapter written by NL Hancox, 'Laminar construction of composites which is required if the reinforcing fibres are to be used efficiently and anisotropy reduced, can be a reason why composite laminates are vulnerable to impact damage.'

Now I have three questions;

1-What is meant here by the specified 'laminar construction to reduce anisotropy'?Does it mean to use different orientation for fibres in each ply to have an isotropic material at the laminate level?

2011 International Dictyostelium Conference, August 14-18, Baltimore, MD USA

Submitted by Tian Zhi Luo on

The annual International Dictyostelium Conference will be held in Baltimore, MD USA from August 14 to 18. Dictyostelium has been extensively used as a model organism for the study of cell mechanics, motility, chemotaxis, cell division and other biological events that involve cell shape change and the mechanical behaviors of cells. In this coming meeting, there will be 70 oral presentations and 100 posters covering above topics.
