Surface:

If it's a free surface, the dislocation can penetrate through the surface easily, but, if it's a coating or oxide layer, it will be hard for dislocation to glid out of the surface

Grain boundary:

In discrete dislocation dynamic simulation, some authors take grain boundary as a impenetrable, such as a rigide wall, But in other papers, grain boundary was thought to be a penetrable wall.

 So,Is there somthing or simillar property for us to derive.

I am studying crack simulations.I am familar with ansys,and i know franc3d files could output into ansys files ,but i don't know how. I just get .fem files from franc3d. But how could .fem files be read into ansys?  Could anyone give me some details?  I'll be very grateful.

Hi everyone,

I just wanted to let everyone know about the upcoming NAFEMS North American 2008 Regional Summit: NAFEMS 2020 Vision of Engineering Analysis and Simulation. This is an excellent opportunity for academic researchers, industrial practitioners and software developers to meet for mutual benefit.

For those of who you not familiar with NAFEMS, it is a non-profit, vendor neutral, engineering analyis community.

Hi ,everyone I find this page very useful ,it has many free mechanical luctures,maybe you well find something useful like me .Please enjoy!

This might be a stupid question but, is it possible to apply loads on a deformed shape in ANSYS? (after applying a set of loads, getting the deformed shape  and applying another set of loads on the deformed shape)

could you please give me a reference about multiscale fluid mechanics?

After some conversation with Roozbeh which are "irritatingly useful" :) I found that this site has done already all the calculations we need http://www.scimagojr.com/  except the list of highlycited papers which remains for me the most interesting aspect and which we seem to need to do manually as we did yesterday with IJSS and JMPS at Most cited papers and H-factor of some mechanics journals -- IJSS

Some results are attached as a big PDF file.
