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.

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:

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..
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.
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:
Seven finalists and three honorable mentions have been announced for the Twenty-Second Annual Robert J. Melosh Competition for the Best Student Paper in Finite Element Analysis. The seven finalists and their current institutions are:
Marcial Gonzalez, Caltech

I often read on books that linear triangles do not have membrane locking for large deformations of plates/shells. I completely don't understand how this is possible. If one uses the well-known CST, stretching is measured as the increase in lenght of each edge of the triangle. Then, in the limit of the membrane stiffness going to infinity, clearly the solution cannot approximate any bending-dominated state, but rather it will be always rigid on general meshes (i.e. Minkowski theorem for convex bodies), allowing at most bending about few lines on very regular ones. What am I missing?
Hello,
I deal with nonlinear behaviour of reinforced concrete structures and masonry structures in my PhD work. I use army manual for defining of pressures of blast load. Now, I want to try model blast load as moving part of air. My problem is, that our university has licence only for ansys, not for ls dyna or autodyn. Do you think, it is possible to model blast wave in ansys flotran? If there is somebody with experience of blast load modeling in ansys flotran, please, I'll be glad for any idea.
Peter
