Investigation of abrasive particle behavior in molecular dynamics simulation
The behavior of materials in abrasive processes are generally quite complex and not fully understood. Empirical relations are the most common way to model these behaviours. Using empirical relations require coefficients which is unique for the combination of materials involved. These coefficients are hard to acquire as experiments for these are complex and time consuming. Molecular dynamics (MD) simulations show potential as an alternative to model the material behavior and empirical relations.

In this project student will investigate the capabilities of MD simulation to model abrasive particle and workpiece interactions. The aim is to acquire empirical coefficients for physical models, such as force and wear to be used in larger scale analysis of abrasive processes. The student will first get familiar with the MD methods and software to use. A representative setup of abrasive processes in nanoscale will be determined and created in simulation. After simulations results will be extracted in the form of forces, material removal and abrasive particle wear. These results will be fit to the empirical models to find physical model coefficients. Depending on the success of simulations, the coefficients will be verified by experiments or compared with literature. Finally, a detailed report will be written to define the guidelines for MD simulation.
