tensile using LIGGGHTS

Submitted by rasoul on Thu, 03/13/2014 - 20:21

Hi,

I have been working on a project regarding compressing and tensile of a solid material.

I had not any problem in compressing part and I utilize "fix X1 all mesh/surface/stress/servo" to do that and the results is perfect.
My problem is in tensile part. When I utilize the previous commend for tensile in one direction, there is no tensile is observed. I implement "Fix move/mesh" for tensile in that direction, but I could not observe any tensile.

I want to know if it is possible to model tensile using LIGGGHTS.

The pair_style which I use is: "gran/hertz/history rolling_friction epsd2"

I would appreciate it if anyone help me.

Sincerely,
Rasoul

You are just putting a granular material under tension? Are you using any cohesion?

As I said, I utilize "pair_style gran/hertz/history rolling_friction epsd2".
I want to model tension in my simulation.
How can I do that?

I don't quite understand what you want to do...As Jon said, tension without cohesion seems to make no sense to me?
