GROWTH of NANOTUBE

Submitted by utpal on

Hi ,

              I have read your post and came to know that you are using
DL_POLY for nano simulation. I am beginners in the field of MD. I am
using DL_POLY_3. Can you please tell me that is it possible to simulate
the GROWTH of NANOTUBE using DL_POLY?

I  am waiting for your reply

thanks and regards

It's heaven in here..! can anybody a chapter of a book online?

Submitted by Anonymous (not verified) on

Hi everyone:

I just joined. found you by chance..you should advertise you know..! I do some modeling of tissue deofrmation and diffusion and stuff. I need to find a chapter of the book "Porous Media: Theory, Experiments and Numerical Application". does anybody have an electronic copy of it or know a free resource where I can find it?

Thank you very much,

Electromechanical instability of large deformation in dielectric elastomers

Submitted by Zhigang Suo on

I attach the slides of a presentation at the ASME meeting.  The talk was based on several recent papers on soft active materials (SAMs).  To give an uncluttered picture of the pull-in instability, I have removed all discussion on the Maxwell stress.   As you can see, the problem can be studied without ever mentioning this troublesome notion.

stable elements for mixed elasticity

I'm very interested in the choice of the finite element spaces for elasticity. I want to choose elements for the stress and the velocity, I was suggested to use piecewise constant for the stress and piecewise linear for the velocities to satisfy the Babuska-Brezzi condition. Is that right? I've heard that I can't use only 6 components for the stress in this way, but I must add some additional constraint to enforce its simmetry. I'm looking for additional documentation, but I can't find any. Has someone got any suggestion? Thanks.

cracking analyses in a bended sandwich beam

Submitted by Ilias I. Tourl… on

I'm studying cracking analyses in a three point loaded specimen of a composed beam.I'm using ANSYS and i want to create codes for estimation of J integral and energy release rate in the vicinity of crack tip.After that i'll calculate the stresses and strains fields,and then i can compare the equivalent fields i retrived using CTOD  and K(I,II,III) factors (according to ANSYS algorithm).

My problem is that I'd like to find a relationship between the above mentioned quantities(J,G)  with K(I,II,III)factors.

News feeds from the IMechE

Submitted by Martin Pratt on

I run part of the website here at the IMechE in the UK. Since we have many international visitors to our technical events I thought I'd point out that we've finally brought out a whole raft of RSS goodness with the launch of a range of industry specific feeds from our calender of events. We intend to launch more feeds for other content areas soon.
