WebIt solely depends on the materials, the surfaces and, of course, which case of friction you're looking at (static or dynamic). Google spat out some coefficient tables that clearly contain values larger than one mostly for same type metal on metal friction. I doubt there's a theoretical limit on it, at some point the model just doesn't fit anymore. WebThe two material coefficients k and f can be determined from fatigue loading tests. The critical plane orientation coincides with the plane orientation where the maximum value of this linear combination occurs. It depends on the material coefficient k.

WebApr 1, 2024 · According to Hutchings and Shipway [36], the specific wear coefficient for metals and ceramics is typically below 10 −4 to 10 −5 mm 3 /Nm at mild wear conditions and varies from 10 −3 to 10 −2... WebDec 15, 1994 · In this research, a realistic friction model, which accounts for the tribological behaviour, and most importantly, the effect of surface roughness on the lubricated contact, is developed. This model has been implemented in a 3-D arbitrary Lagrangian Fulerian finite element code for metal forming analysis.
