Question about friction in situation where interface slip occurs

Click For Summary
SUMMARY

The discussion centers on the "stick-slip mechanism," a phenomenon occurring at the interface between two components when external forces exceed the friction force, leading to slip. Once slip occurs, the components reach a new static equilibrium state where static friction applies if there is no further slip, despite potential deformation. The challenge lies in quantifying stress, strain, and deformation in these scenarios, making it a complex topic for precise predictions.

PREREQUISITES
  • Understanding of static and dynamic friction coefficients
  • Knowledge of stress and strain concepts in materials science
  • Familiarity with equilibrium states in physics
  • Basic grasp of the stick-slip phenomenon
NEXT STEPS
  • Study the stick-slip phenomenon in detail using resources like the Wikipedia page on the topic
  • Learn about quantifying stress and strain in materials under deformation
  • Explore static and dynamic friction coefficients in various materials
  • Investigate applications of the stick-slip mechanism in engineering contexts
USEFUL FOR

Mechanical engineers, materials scientists, and students studying friction and deformation in physical systems will benefit from this discussion.

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 occurred, 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
