Wear is modelled on the contact zone level so as to retrieve the mechanisms of the meso-scale within the macro simulation. The project therefore contributes to the simulation-based design of tool surfac-es with an improved durability. The model does not implement any Archard model, but simulates abrasion mechanisms directly at the mesoscale level - abrasion results from separation of surface material. This type of modelling enables a mechanism-based prediction of wear behaviour and thus contributes to the understanding and design of the tribological system. The methodological approach shall draw on and further develop the Particle Finite Element Method for the underlying solids and the lubricant.

在接触区水平上对磨损进行建模，以便在宏观模拟中检索细观尺度的机制。因此，该项目有助于基于仿真的设计工具表面，提高耐用性。该模型不执行任何Archard模型，但直接在中尺度水平上模拟磨损机制-磨损是由表面材料分离引起的。这种类型的建模能够实现基于机理的磨损行为预测，从而有助于摩擦学系统的理解和设计。该方法应借鉴并进一步发展用于基础固体和润滑剂的颗粒有限元法。
