Hi all,
I have a strange question that has puzzled me since last almost one year.
There are many SG-plasticity models in the technical literature, sometimes categorized as lower-order or higher-order models.
The problem is :
the constitutive models include the gradient of plastic parameters (e.g. plastic slip).
Hi, guys,
Do some of you know how Periodical Boundary Condition is implemented in equilibrium equation while using FEM:
div{ C:sym[grad(u)] } = 0 ,where the displacement u is periodical.
Is there any (detailed) documentation about this stuff?
Thank you very much!
Hi,
Is there a free/open-source mesher for the Spectral Element Method?
I know some researchers use conventional mesher with order 3 elements and then include more nodes in the meshes (but without improve the geometric interpolation).
Thanks in advance,
Nicolás Guarín Z.
There is an immediate opening for a Ph.D. student in the Department of Materials Science and Engineering at Missouri University of Science and Technology (Missouri S&T - formerly University of Missouri-Rolla). The Metallurgical Engineering program at Missouri S&T is one of the largest and most respected in the U.S. (http://mse.mst.edu).
The Ph.D. research project is about developing a coupled phase-field crystal plasticity model for predicting stress-strain-microstructures relations during deformation.

The individual project:
“Finite-element modelling of electromechanically coupled materials”
will be hosted at University of Duisburg-Essen (Germany), www.uni-due.de/mechanika, with secondment to the University College Dublin (Ireland).
This position has been filled.
Can you define FEM in one line?
If yes, what would it be? And, in that case, permit me a second question: How?
...Really interested in knowing what the members of this community think (of this matter), if they do...

Dear All,
I am currently working on a small academic project of Damage Detection of Bridge Structure using Vibration Frequency and Modes analysis and Finite Element method.
My questions are:
1) Is there any systematic approach to follow this problem?
2) How should I start making its mathematical model? I am considering a truss bridge. Is it appropriate to consider linear elastic deformation of simply supported beam at first point?
3) Is there any standard reference which can help me to construct its mathematical model?
