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

Submitted by haiyang song on

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

Relation between particle size and debonding stress

Submitted by CeciliaPisano on

Hi everybody,

do you know where I can find some informations about the relation

between particle size and critical normal stress at the interface particle /matrix

for a particle embedded in a matrix?

I read the Chen's article 'Size effect of particles on the damage dissipation in nanocomposites'

but this article deals with spherical particles. I am studying clay/matrix nanocomposites and I would like to

calculate the relation between clay size and debonding stress.

Thanks,

Cecilia

Twitter and iMechanica

Submitted by MichelleLOyen on

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. 

0 Thickness Cohesive Zone Modeling

Submitted by henryjamesusa on

Hi friends:

This is Henry, a graduate student in USA.

I am recently trying to model a 0 thickness cohesive zone with curvature and I realize that by using mesh edit.

When I made it and submit the job, the ABAQUS always told me the node numbering has a problem and thus abort the job.

Does anyone who has experience with that?

Thanks.

Henry.
