Constant Normal Load for Direct Shear Test

Asked by Akm on 2019-08-27


I am a beginner in Yade trying to create the simulation for a direct shear test. I am using a faceted box to create the sample.
But I am unclear on how to provide a constant load at the top plate to simulate the condition.

 I tried to use the triaxial stress controller but couldn't do it as the top box of the sample has to move horizontally and Triaxial stress controller doesn't work that way. Kindly let me know your suggestions on how to achieve this.

I can upload the code in launchpad if you need to take a look. If someone could upload an example code for direct shear, I would be more than happy.

Please see replace therein "KinemCNSEngine" with "KinemCNLEngine".

PS : I guess one has to be very optimistic to hope a "triaxial" stress controller may simulate a direct shear experiment ;-)

Hi Jerome,

Thanks for the tip. I did not mean to use triaxial to simulate the direct shear experiment, I only wanted to impose a constant normal load on the sample using the engine and then set the upper box with a prescribed constant horizontal velocity.

Can you help with this problem?
