contact parameters

[Wangyun]

Dear STKO team
How can I determine the parameters: Kn, Kt, mu when I use the zerolengthcontactASDsimplex?
What is the meaning of these parameters?
Is there any relevant paper reference?
Thank you for replying.

Dear Wngyun,
Kn: Normal stiffness. It is the Elasticity modulus in the normal direction to the contact element. You can assume 10~100 times the smallest value of E of the elements in contact.
Kt: Shear stiffness modulus. It is the Elasticity modulus in the tangential direction to the contact element. You can assume 10~100 times the smallest value of G of the elements in contact.
mu: friction

Dear Horace Horsecollar

You can assume 10~100 times the smallest value of E of the elements in contact.

Why is the parameter determined in this way? Are there any references?

There are several publications please check in the literature

Dear Francesca
Your staff referred me to that example, but I did, and now there's a problem, and no one's fixing it.
Please solve it as soon as possible.
Thank you very much
