Postdoc position in Bioacoustics
Postdoc position is currently open in my group. The research revolves around bioacoustics of marine animals (mammals and fish). The goal is to understand the mechanics of sound production and hearing. Research directions include formulation of specialized finite element models for biological materials, mesh generation from biomedical images, and models for attenuation in tissues. Funding is available for at least one year. Contact: pkrysl-at-ucsd.edu.
representative elementary volume of non-local continuum
Dear mechanicans,
For non-local continuum, is there a proper approach to determine the size of the REV in experiment? For the classical linear elastic continuum, one can measure the homogeneized stress and strain (or local averaged stress/strain) and compute a homogeneized elastic constitutive tensor. However, I am not sure how to do it for non-local continuum, since the constitutive response is now sensititve to the gradient term. Any comment/suggestion is appreciated.
Regards,
WaiChing Sun

Hi Everyone,
I have a general question about dynamic strcture problem,
I read from some books that "spatial resolution of high-frequency modes typically is poor by using the conventional finite element spatial domain discretization"?
Could someone explain more on this? Does it because the element usually is not fine enough to capture the high frequency response or...?
Thanks a lot!

Hi everyone
Can anyone advise on how to select stress values at specific points in a model once the job is executed?
I am interested to extract the stress values from specific points (nodes) in a model.
Many Thanks.

Notch stress distributions
Dear all,
this is for all people interested in notch analyses.
In the links below you can find some recent works of mine about linear and nonlinear stress distributions for different kind of notches under torsion.
Hope they will be useful to someone:

Slope of The Non Linear Stress Strain Curve at Proof Stress
Dear All
Hi..
Can Any body tell Me The calculation of the E_t Tangent And E_s Secant Modules VAlues of the Stress Strain curve?...
i had go through some of graphs but i dont get it?..it will be help ful to understanfd the E_t And E_s?..
i had values of Stress and Strain and also a Stress strain curve available..
Plz do need ful..
How to assign cohessive material to a surface?
Dear friends
I am modelling composite delamination using ABAQUS, i used 3D elementsin my model. my question is that how can i assign cohesive properties to a cohesive surface between to solids?
Should i treat the cohesive section like a continuum with thickness?
Is there any way exept the last one?
Is there any other aproach to model delamination?which one is better?
Thanks.
IMECE 2010 - Minisymposium on Multiphysics Simulations and Experiments for Solids
Dear Colleagues:
We would like to invite you to submit an abstract for the 2010 ASME IMECE in Vancouver, to be held November 12-18, 2010. Our minisymposium is on "Multiphysics Simulations and Experiments for Solids", and is the continuation of a very successful minisymposium held at the 2009 IMECE that resulted in more than 50 presentations. This year's focus areas are:
