2.13. Mathematical Formulation

The Archard wear model is a shear-based model that correlates volume losses with the work due to friction forces (Figure 2.13: Application of the Archard wear model in Rocky DEM simulation. ). This model has been extensively correlated with a wide variety of materials and is frequently used by the mining industry to simulate wear. The following equation shows the application of the Achard Wear Model in Rocky DEM simulation:

(2–5)

where:

  • is the volume of material worn from surface.

  • is the shear work.

  • is the user input parameter Shear Work Proportionality.
