Archard Wear Modeling in Ansys Mechanical Using Contact Information

Archard wear modeling can be a powerful method for determining the effects of wear in your Ansys Mechanical model. Using the Archard wear function through APDL commands, you can control material values and use your model's contact pressure and relative sliding velocity to induce physical wear. This implementation allows you to visualize geometry change due to wear and calculate the wear volume that occurs throughout the simulation. In this video, we demonstrate how to simulate wear between rotating contact surfaces using a 2D axisymmetric model, nonlinear adaptive meshing, and user-defined contact results in Ansys. The example model uses a rotating copper ring pressed against a stationary steel ring to demonstrate how wear evolves over time and how adaptive remeshing maintains solution stability during large deformation and contact element distortion. ---------- CHAPTERS 0:00 Introduction 0:58 Model Setup 2:29 Contact Formulation 3:28 Archard Wear APDL Commands 4:31 Wear Equation Explained 5:12 Adaptive Meshing 5:44 Results Review 6:35 Wear Depth Results (NMISC 87) 7:24 Limitations and Best Practices 7:55 Conclusion ---------- Check out our library of resources from blogs, case studies, white papers, and webinar recordings: https://www.drd.com/resources/ At DRD Technology, we know sophisticated software is only as powerful as your ability to utilize it effectively.
