Interface Between Plate and Specimen Modeling

3DEC
1

Hello,

I am trying to run UCS on cuboidal specimens (consisting of deformable tetrahedral blocks) of different width-to-height ratios in 3DEC. The goal is to calibrate all w/h ratios model peak strength with a single micro-property set. Therefore, I am trying to use the interface friction angle between the plate and specimen (to generate some confining stress due to boundary constraints). For that, I am creating the geometry first and then populating it with the tetrahedral blocks. After trimming the sides, I created the top and bottom plates using the brick command. I just want to confirm, is it the best way to create an interface between the plate and specimen or do I need to use some other commands to create the interface?

Thank you for your help.

This looks fine. You can convince yourself that it is working by plotting the joint planes. You will see a continuous joint plane at the top and bottom between the platens and the voronois. You just need to assign the approriate contact properties to these planes.
