Static friction in solids is explained by considering disorder on a multiasperity scale. This approach reveals smaller Larkin domains, accounting for the universal occurrence of static friction between contacting elastic solids.

Area of Science:

  • Solid Mechanics
  • Tribology
  • Materials Science

Background:

  • Previous research indicated large Larkin domains at disordered interfaces of nonmetallic elastic solids.
  • This suggested negligible static friction in the macroscopic limit.

Purpose of the Study:

  • To investigate the scale of Larkin domains considering multiasperity disorder.
  • To provide a theoretical explanation for the widespread observation of static friction.

Main Methods:

  • Calculation of Larkin domains on a multiasperity scale.
  • Theoretical analysis of static friction in contacting elastic solids.

Main Results:

  • Larkin domains are significantly smaller than the interface size when multiasperity disorder is considered.

  • This scale reduction provides a mechanism for static friction.

    • Conclusions:

    • The universal occurrence of static friction is explained by the reduced Larkin domain size due to multiasperity disorder.
    • This finding reconciles theoretical predictions with experimental observations of static friction.
