    Status: Open => Needs information

Jan Stránský requested more information:
Hello,

> What I am gonna ask is a simple question.

Actually it can be very complex :-)

> If I know the normal and shear stiffness kn and ks of spheres, how can
I determine the corresponding Young's modulus E and Poisson's ratio v? E
= kn * D (radius of sphere)?

What is "the normal and shear stiffness kn and ks of spheres"?
What materials and contact law(s) are you using?
What is "the corresponding Young's modulus E and Poisson's ratio v"?

Cheers
Jan
