Worldwide Electroactive Polymer Newsletter

Submitted by Zhigang Suo on

The latest issue of the WW-EAP Newsletter is now available.  I’m pleased that the issue includes my submission on a recently completed review on the Theory of Dielectric Elastomers.  As usual, the Newsletter contains lots of extremely valuable information, such as new books in the field, and new products.

Abaqus UMATs

Submitted by Lee Margetts on

I have funding for software development to provide a UMAT interface in the parallel versions of the code from Smith I.M. and Griffiths D.V. "Programming the Finite Element Method", 4th Edition, Wiley, 2004.



I would be interested to hear about any open source UMATs available for download. I'd also like to hear from anyone who might like to use their closed source UMATs in a parallel environment.



The funding has been awarded by the UK National HPC Service HECToR to encourage the greater use of HECToR for Structural Engineering.



Soil Mechanics and Fossil Dinosaur Trackways

Submitted by Lee Margetts on

My PhD student Peter Falkingham (who graduated 15 December 2010) has published some interesting papers on Dinosaur Trackways. These might be of interest to those teaching Soil Mechanics, to give some examples that might be more stimulating than foundation design or traditional geotechnical engineering.

ABAQUS:Negative Pressure with “Hard” Pressure-Over Closure

Submitted by thanu on

Hi,

I'm using ABAQUS for my research o soil-pile interaction. For the initial modeling of soil-pile interface I have used the "Hard" pressure-over closure relationship. According to the definition negative pressure is not possible with that type of normal contact behavior. But when I check the contact pressure still I can see that negative pressure is applied. What could be the reason?

Thanks,

Thanu

Boundary Conditions in ABAQUS, Phython

Submitted by Svetlana Orlova on

hello everyone!

I have a parametric model in ABAQUS. One of the surfaces has many faces and to set a displacement, for example, I need to select all the faces on this surface. One of the ways  to pick them is to use faces.findAt(), but the problem is that there are over 100 faces on this surface and I don't know their coordinates because I used "random" function to create them. Do you know how can I specify the region? I've tried to pick the whole surface instead but I couldn't...
