I Question about friction in situation where interface slip occurs

[ohmyshoulder]

Hello, I have question about friction at inteface between two component

slip occurs at interface when external force bigger than friction force(= normal reaction force * static friction coefficient)

After slip occured, component motion stopped and got new static equlibrium state

In this state, how force applied at interface? static friction applied? dynamic friction applied? or other case?

... got new static equlibrium state

In this state, how force applied at interface? static friction applied?

If there is no slip anymore, but the object is still deformed, then you have static friction.

Thank you for applying!

I got theory about this problem named "stick-slip mechanism"

It's so hard problem to understand.

I would have to study a lot

thank you

It's not difficult to understand conceptually:

But it is difficult to predict quantitatively for specific objects.

I have to quantifying stress, strain, deformation in this situation.

It's a hard problem
