contact parameters

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
Regards

Dear Horace Horsecollar

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

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
