Subproject C6
Multiscale Modeling, Simulation and Optimization of Cutting Tools Regarding their Tribological Behavior
Overview
The objective of subproject C6 is to model the wear of mining tools from the microscopic level up to the macroscopic part and therefore to obtain a deeper understanding of the involved processes like abrasion and surface disruption. For this, mechanisms such as plasticity, damage and crack propagation must be numerically implemented across scales and coupled with each other, which still brings up the major challenges in solid-state mechanics.
The aim is gaining the knowledge for reliable predictions for the life of the cutting tools depending on the nature of the excavated soil. In a further step, the geometry and structure of the mining tools as well as the microstructure of the considered materials are to be optimized regarding the predicted lifetime.
