i can see that from macro scale to nano scales the friction coefficiente is totaly diferent, the amonton's law it can't use it at nano scale, because the plastic deformations.
Hello, I am student of Master degree about geotecnic here in Chile. So I am traing to solve the next problem.
What happened with static coefficient of friction when the normal pressure increase from zero to very high values.
For any material, Is it the same value of the coeffient of...
