Question about friction in situation where interface slip occurs

In summary, the discussion focuses on the mechanics of friction in scenarios where slipping occurs at the interface between two surfaces. It highlights the complexities of frictional forces when one surface moves relative to another, emphasizing the transition from static to kinetic friction and the factors influencing this behavior, such as surface roughness, material properties, and external forces. The analysis aims to clarify how these factors affect the overall frictional response in slipping situations.

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?

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
