Abstract: In a method for evaluating mechanical tests of a coating on a substrate, in a first step a mechanical stress is applied onto the coating, in a second step the substrate having the coating is isothermally clamped, in a third step an infrared photograph is generated of the region in which the mechanical stress is applied onto the coating in the first step, and in a fourth step the infrared photograph is evaluated. A device is arranged for carrying out the method.
