Contact forces in DEM based PFC3D software?

01 January 2019 0 5K Report

Hi everyone,

I am using PFC3D to model CPT push in specimens with particles with different rolling resistance coefs. I am getting some contact forces that seem not right. As far as I know, contact forces for the specimen with larger rolling resistance should have stronger than the one with the smaller value of rolling resistance, but what I get is different. Any idea what the problem is? I have the figures attached for your review. Thanks for the help.

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
