Dear imechanica Members,
Hi!
I am investigating the effect of triaxial stress state on the superelastic behavior in NiTi. In this regard I have conducted some simple tensile tests on notched specimen until fracture. The next step is to investigate the fracture surfaces in SEM to determine point of initiation and the structures. However, as my knowledge in fractography is limited at best, I am not really sure what to look for to determine eg. fracture initiation.
In May 2008, I posted 3 lectures on Soft Active Materials given at UCSB. I have since given similar lectures on other occasions, but never all three at the same place. The field has been active. The lectures have been updated with new items. I’m now posting the “2nd edition” of these lectures.
The slides are posted as delivered. No effort is made to eliminate repeating slides.
Hello all
I have spent a large amount of time trying to undertstand the multiscale aggregating method (MAD) of Prof. Belytschko. Unfortunately, I still can not compltely understand the method.
If there is anyone here in the forum already gets clear about the method, please help me.

(Question tranfered from previous blog post)
Dear iMechanica members,
Can ABAQUS or other commercial software's user material be reseased as open source code? GPL for example? If so, whith the multiple licenses proposed, which one would be most
suited for releasing vumat source code. The intent is simply to make
this vumat available to as many people as possible without anyone
taking undue ownership of the material law. Also, would there be any concerns about publications or articles concerning said material law once the source code is public?
