Contact Mechanics is a fundamental discipline of the engineering sciences. Every system - technical device or living being - is composed of connected parts, which makes Contact Mechanics relevant for countless physical, technical, and medical applications. In mechanical engineering alone the scope is immense, examples include bearings, gears, clutches, wheels, brakes and many more. In recent years, the area of Contact Mechanics has conquered new fields of applications which are at the forefront of global development trends in technology and society. Fields of micro-technology, biology and medicine have been particularly important additions. Further applications are the adhesive strength of bonded joints, turbine blade connections in jet engines, extraction methods of broken implants, advanced methods for material testing, and friction damping of aerospace structures.

From a numerical perspective, a particular focus of the department is on the FFT-based Boundary Element Method. This simple and efficient method is currently the fastest numerical technique for the simulation of rough surfaces and adhesive contacts. Two exemplary papers can be found below.
