It is really a long time since my last post about research stuff, emmh?
This pix is generated using the shear-strain coloring in atomeye, and it shows the cross section of a Ni3Al column in compression test. From it you can easily tell that the most highly stressed area is actully the surface.

A PyMol generated gif file

This is the gif file showing how dislocation would grow in a

twenty-Angstrom radius Ni3Al sample when compressed. It is quite

impressive, beautifully shows how dislocations and slip planes grow and

interact with each other.

I have tried to use Protein Explorer before turning to PyMol. PE, as I

think, is too much tricky to manipulate and very picky on browser as

well. But all the things in PyMol are easy, you simply click some thing,

almost everything can be done! I do not know why there is even less

document on PyMol on the net than rasmol and PE. Perhaps that is due to

PyMol is a young software, hmmm?

Python rocks, sourceforge rocks!

Coordinate number method

This is picture is plotted completely at the same step as last one. This

time I use the coordinate number method to plot it. It is beautiful as I

have imagined.

What the hell is it? Some kind of visual maze?

What the hell is it? Some kind of visual maze?

My supervisor ask me to plot out the morphology of the dislocation in

the compression simulation of Ni3Al. I got this when trying that using

relative displacement method. It shows the cross section area, and looks

like a maze, isn’t it? Perhaps I should also try potential energy and

coordinate number, which might give me different image. Hmmm…

I think I am much nearer to the key.
