The School of Aeronautics and Astronautics of Zhejiang University invites applications for a full-time distinguished professor position in the field of solid mechanics. The successful candidate should obtain an earned phd degree from world famous university, must have an excellent academic record, and currently takes full professor or comparative position in overseas world famous university or institute.
On behalf of the NSF Summer Institute on Nanomechanics, Nanomaterials, andMicro/Nanomanufacturing, I am writing to remind you that the deadline for application for fellowships is March 1, 2009, for the short course entitled "Multiscale Science Based-Modeling and Simulation and Experimental Validation on Enabling Materials", to be offered from May 27 to May 30, 2009 in Evanston, Illinois. The short course will first cover science-based modeling and simulation methods for general classes of enabling materials.
Hello,
I'm trying to simulate and compare principal stresses in model of bolt and nut, for different material data. I would like to get the soft/hard stage comparison. The problem is that I just do not know how to define hard stage material, it is not in standard material library in ansys (workbench or classic).
If anyone could help me giving some examples of hard stage materials data I would be greatfull.
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.
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 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.
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.
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.
