Layman Description:

During the course of his PhD studies, Mads Krabbe has carried out research into fracture in hard, thin films. These thin films are typically used to enhance the wear resistance of machine parts and they include titanium nitride (TiN), aluminium oxide (Al2O3) or diamond-like carbon (DLC).

Mads Krabbe has combined analytical models and numerical calculations to simulate the propagation of cracks in thin films during loading. Hard, brittle thin films often fail by propagation of cracks in the films. The cracks and their propagation are of vital importance for the wear resistance of the thin film. The propagation of cracks is controlled by the fracture toughness of the thin film. The fracture toughness is an essential parameter for the wear properties of the film. Methods to determine the fracture toughness exist today. However, these methods are either inaccurate or require advanced equipment. In his studies, Mads Krabbe developed a new method to determine the fracture toughness of the thin films using more simple equipment.
