This conference will take place in Hawai'i, USA, 11-14 December 2011
Themes covered will include:
• Natural, biologically inspired and biomimetic materials• Hard (e.g. bone, teeth, metals, ceramics) and soft (e.g.cartilage, tendon, silk, polymers) tissues and materials• Mechanobiology, regenerative medicine and tissue engineering• Multiscale modelling and simulation of mechanical properties• Multiscale experimental characterization of biological tissues, including AFM, nanoindentation, optical tweezers
Hi my friends,i am using Dracker prager plasticity model to simulate uniaxial compression (softening) of coal samples.in dracker prager, the shear criterion is linear, and the hardening type is compression. there is a table that i should fill out, this table composed of yield stress and abs. plastic stain. my question is:- how can i fill out this table by using the experimental data (stress-strain diagram for uniaxial compression test) ?? shall i convert these data using any equations??
The postdoctoral researcher will develop three-dimensional, network-like
models for fluid displacement in low permeability porous media. Such
porous materials involve multiple relevant length scales (e.g. micro-fractures
connected to the adjacent matrix) and models to date are not representative.
This research-only position will be supervised by Drs. Maša
Prodanović and Steven L. Bryant from Department of Petroleum and Geosystems Engineering, University of Texas at Austin.

Dear All,
I am wondering that is there any closed form solution for beam on elastic foundation in case which we have got two stiffness for the springs namely (axial and shear stiffness). The axial force are born because of the some loading conditions in the support.Would you please help me about this?
Thank you,
Parisa
I am simulating the tensile test of steel specimen to confirm that
resulting force displacement data matches with experiment. Since the
true stress true strain formulas are not valid beyond necking i have to
rely on actual neck measurements of flat sheet geometry. I have
identified swifts parameter also to use in the material model but some
how i am unable to match my results beyond necking. Any suggestions??
Dear Colleagues:
Wing Kam Liu and I (Ashfaq Adnan) would like to invite you to submit abstract(s) to the following mini-symposium at the upcoming 11th U.S. National Congress on Computational Mechanics (http://www.usnccm.org/). The congress is scheduled to be held on July 25-29, 2011 in Minneapolis, Minnesota, USA.
14.2 Multiscale Transport Phenomena in Biological and Biomedical System
We have studied the elastic response of actin networks with both compliant and rigid crosslinks by modeling molecular motors as force dipoles. Our finite element simulations show that for compliant crosslinkers such as filamin A, the network can be stiffened by two orders of magnitude while stiffening achieved with incompliant linkers such as scruin is significantly smaller, typically a factor of two, in excellent agreement with recent experiments.
Hello everybody,
I need some help. I have a lot of problems trying to implement the MMA or GCMMA optimizer in the Sigmund's Topology Optimization code (99 lines). Have you ever do that?. Please, is very important for my pregraduate thesis.
Thanks.
