Further question on mesh/surface/stress/servo

Submitted by wangyin47@gmail.com on Thu, 07/10/2014 - 12:42

Hi, there
I am trying to implement a tri-axial compression test to calibrate the parameters for contact model.
There could be two geometry for sample, cylindrical and block, right?

How to keep the pressure constant on the meshed wall as the lateral wall area varies under compression?
And another thing, for example, for the cylindrical sample, how to implement a targeted force on the cylindrical wall towards radial direction?
cheers

Hi,

for a block geometry you could use multiple fix mesh/surface/stress/servo commands

For a cylindrical wall, there is currently no out-of-the-box functionaility to control the stress

Best wishes
