Corotational formulation for 3D solids

Please have look 
http://arxiv.org/abs/1110.5321
 
This paper presents the theory for the Lagrange co-rotational (CR) formulation of finite elements in the geometrically nonlinear analysis of 3D structures. In this paper, strains are assumed to be small while the magnitude of rotations from the reference configuration is not restricted. A new best fit rotator and consistent spin filter is derived.

New International Master Program in Computational Materials Science

Hi,

I am writing to inform you about a new master in Computational Materials Science offered at TU Bergakademie Freiberg, Germany. It is an international master program, and all the lectures will be given in English.

To enhance multidisciplinary research, the program is open to students from different background, mechanical engineering, solid state physics and materials science.

 

Finite element simulation of substrate and film

Hello Everybody here :

 I am going to use ANSYS to do some finite element simulations of interface crack between

substrate and film and the residual stress of substrate and film. I don’t how to define the interface of the substrate and film in finite element model. How to connect the substrate and film? Just glue the substrate and film or use other element to deal with it? Thanks a lot.

Open-source finite element code

Hello everybody,

I just wanted to let those interested in Matlab finite element development and educational environments that the successor to the SOFEA toolkit is now available at

http://hogwarts.ucsd.edu/~pkrysl/faesor

The toolkit now provides in addition to thermal and stress analysis (static and dynamic) also sample simulations from other fields, such as acoustics, nonlinear heat conduction analysis, electrostatics, small-strain plasticity, .... The toolkit now also includes an implementation of the Nodally Integrated Continuum Elements (NICE) which are quite effective for nearly incompressible mechanics problems.

The toolkit and the accompanying textbook are open-source and freely available. The book is also available in print.

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!

BR,

Li

In search of articles on mesoscale FE modeling of sintering

Choose a channel featured in the header of iMechanica: 

Hi. I'm now starting my PhD on a project on sintering of hard metal.

I'm doing a literature study, but I have failed to find any articles that uses FE analysis on the micro/mesoscale. All of them seems to handle this only with a homogenized model on the macroscale.
If I get to be picky, I would prefer something with hardmetal, but at this point, anything would be great.
I would also be very happy to find any suitable reading on FE-analysis on solid-liquid-pore mixtures.

Teeth implant Finite Element Analysis

I am looking for a Finite Element software for Teeth and Implant modeling and analysis. Is there a special FE software for this, or which of these softwares can solve the proplem.

Abaqus, ProEng, Ansys, catia, solidworks, or anyother software..

please, if you know about solving this problem, share your thoughts with me.. or send me a link to this kind of analysis...

thanks to all in advance...

Elasto-plastic theory - ABAQUS

Hello,

 

I have started to study the plasticity theory few months ago. I'm trying to do one exercise in plane strain of one elasto-plastic material in ABAQUS and manually.

When the load is small, the material has just deformed elasticly and the total and elastic strain in z-direction (E33 and EE33) are zero (like say the theory of plane strain). 

Deadline Extended for 21st Annual Melosh Competition

The deadline for abstracts for the 21st Annual Melosh Competition has been extended until January 30.  All interested graduate students are encouraged to apply.

 This competition for the Best Student Paper in Finite Element Analysis will be held at Duke University on Friday, April 24, 2009.  The competition has become one of the premier graduate student events in the broad area of computational mechanics.  

Glass thermal stress and fracture

I have an investigation on glass fracture in fire.

I have a fortran program and it can calculate the thermal stress with steady-state temperature and force load using finite element method, Now I want to change it to transient temperature and force load.

I wonder which method should be taken? I'd like to calculate the fracture at last.

Please help me! 

Thank you very much.

you can email to me : q.wang@kingston.ac.uk or pinew@163.com

Predictive modeling schemes for wear in tribometers

Choose a channel featured in the header of iMechanica: 

Study of wear in complex micro-mechanical components is often accomplished experimentally using a pin-
on-disc and twin-disc tribometer. The present paper proposes an approach that involves a computationally
efficient incremental implementation of Archard’s wear model on the global scale for modeling sliding and
slipping wear in such experiments. It will be shown that this fast simplistic numerical tool can be used to
identify the wear coefficient from pin-on-disc experimental data and also predict the wear depths within a
