Failure of protein materials in disease and other extreme conditions
The recent issue of Nature Materials includes a review paper on the deformation and failure of protein materials in physiologically extreme conditions and disease. The paper was interesting, so I am posting the abstract here. For the full-paper visit Nature Materials.
UMAT: Calling a another subroutine in UMAT, Errors during job execution
Hi,
I am in process of implementing the Bergstroem-Boyce Model. In a first
step I am just considering the hyperlastic part of it (Network A:
8-chain). I have implemented this part in a UMAT using a numerical
approach for the elasticity tensor (Forward Difference Approximation
with perturbation of F).
I have two problems:
1.
------------------------
In order to keep my UMAT as easy to read as possible I have tried to keep the FDA in a separate file using
call KFDA_Jaumann(dfgrd1,......)
A recent paper about friction laws at the nanoscale
A very recent paper published a few minutes ago in Nature addresses the issue of friction laws at the nanoscale. Here is the abstract of the paper.Interested? here you can download the paper.
ASME Congress 09 on the Mechanical Behavior of Nanocomposite Materials
You are invited to present your research work on the mechanical behavior of nanocomposite materials (Nov. 13-19, 2009 in Florida, close to Disney World). This topic will be focused on systematic mechanics experiments, modeling and simulations to solve new challenging mechanics problems such the effect of nanofiller agglomeration on the stiffness and strength reduction; interfacial stress transferring and interface strength evaluation at the nanoscale. Deadline for abstract submission is March 17, 2009.
An article on tenure-track
Stop Trying To Get Tenure and Start Trying To Enjoy Yourself
One of my junior colleagues forwarded the above article to me, and I read with interest. I think it could also resonate the interest of many people here in iMechanica. I welcome your comments, especially from our been-there done-that tenured colleagues.

Okay, I have used this quote a lot and have probably misattributed it. Who first said, "All models are wrong. Some models are useful."?
