Failure of protein materials in disease and other extreme conditions

Submitted by azadpoor on

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

Submitted by Andreas Burger on

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,......)

ASME Congress 09 on the Mechanical Behavior of Nanocomposite Materials

Submitted by L. Roy Xu on

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.

Nominal stress Vs Nominal strain plot in FE simulations

Submitted by Gouse on

Hi all,

 I want to plot nominal stress Vs nominal strain plot from my FEA simulation. In generally I will get stress and strain at element level, now how can I plot stress-strain for the overall struture. I am applying uniaxual load on specimen. My analysis is non-linear.

Thank you

Regards
