Dear Wojtek ,
Visit the following links of Wikipedia (A magnificent source of applied knowledge)
http://en.wikipedia.org/wiki/Young'smodulus
http://en.wikipedia.org/wiki/Elasticmodulus
http://en.wikipedia.org/wiki/Poisson%27sratio
Hope to have helped you

Thanks
So I can directly use equation k=EA/L for spherical particles?
Where:
L=d (diameter)
A=(pi*d^2)/4
I'm using PFC3d, and I read about contact Young's modulus in a user's guide, which is suppose to be different (and reffering to the manual - greater than "normal" Young's modulus) ■
Particle Stiffness
Hello, I'm new here. Currently I'm working on some DEM simulations. I would like to know if enybody here could tell me how to obtain a stiffness of particles. Let's say I have a substitionary radius, Young's modulus, Poisson's ratio etc. I've found some equations, but I don't know if they are suitable.
I would be grateful for any help
Thanks in advance
Best regards ■
