Wear modeling in EDEM - Archard Abrasive Wear Model with Geometry Deformation
Altair EmployeeOverview
Abrasive wear is an important phenomenon in a wide range of applications where the particles of a granular material slide against equipment surfaces.
The Archard wear model is widely used for the DEM modelling of abrasive wear.
The model computes the volume of removed material due to abrasion. The corresponding depth of wear on CAD geometry mesh elements is computed in EDEM. This enables the modelling of geometry deformation due to abrasion and a version of the model with this feature is attached here.
Update September 2024: This model has been updated to the version 3.7 of the API and now it works on CUDA GPU as well.

Usage/Installation Instructions
After selecting the model in the Particle to Geometry interaction in Physics section of the Creator, click on the wheel button to specify the wear constant. Note that it is not necessary to define the wear constant for all interactions For further details please refer to the attached PDF document and download the ZIP file to use the model.
