The effects of boron dopings and boron grafts on the mechanical properties of single-walled carbon nanotubes

Submitted by haiyang song on Tue, 10/27/2009 - 09:19

research

The effects of boron doping and boron grafts on the mechanical behaviour of armchair (6, 6)

and zigzag (10, 0) single-walled carbon nanotubes (SWCNTs) under axial loading are

investigated using the molecular dynamics (MD) simulation method. The results show that

Young’s moduli, the tension strength, the buckling loads and the buckling strains of SWCNTs

decrease after functionalization. The influences of the distribution density of functionalization

on Young’s moduli of SWCNTs are also systematically studied. The results show that Young’s

Tsai-Wu FC

ansys

Good evening,

in the order to perfom a calculation of Tsai-Wu Fc in Ansys there are two fundamentally different methods:

1. with the help of nodal stresses.

2. or with the stresses from the element table.

I want to know what is the difference, and which method, according to your experience is the best.

Thank you very much!

Embryonic stem cell softness dictates stress-induced spreading and differentiation

Submitted by Ning Wang on Mon, 10/26/2009 - 14:24

research

We recently find that embryonic stem cells are very sensitive to a local cyclic stress applied to the focal adhesion. They spread and differentiate (Oct3/4 downregulation) in response to this local force.

Umat-Help-Progressive Damage modeling

Submitted by rajeshkatta on Mon, 10/26/2009 - 09:41

Composites

Hiii All,

I am writing an umat for Progressive Damage modeling for 3d Composites.

when I am compiling my Umat i got an error which says

The executable /raid/software/64/abaqus/6.8-1/exec/standard.exe

aborted with system error "Illegal floating point operation" (signal 8).

I checked out my code many times but i dont find any wrong,Can any one please help me out to resolve this issue.

If some one needs my subroutine file i can send it to them provided te email address

Twitter and iMechanica

Submitted by MichelleLOyen on Sat, 10/24/2009 - 20:12

How many iMechanica users are on Twitter? And how many are on Twitter with professional contacts?

I started to use Twitter about 4 months ago in a completely social, non-professional context. As a personal (expat-focussed) blogger, I started to notice that I was
catching blog posts in my Twitter feed before I would see them in my
feed aggregator (Bloglines). Twitter has emerged as a different sort
of feed aggregator, as well as a provider of information.
