Abstract: The present invention relates to a method for manufacturing a product with a spatially structured surface from a semi-finished product, a semi-finished product required for this purpose and a product produced in this way. The method is characterized in that a patterned target bending location is produced in the semi-finished product, and in that the semi-finished product is then subjected to a pressure over its surface, which is dosed in such a way that the pressure causes a plastic deformation of the semi-finished product along the target bending location, so that a product with a spatially structured surface is produced.

Abstract: A connection between at least two joining partners includes an interlying joining gap, with opposite joining surfaces. At least one of the joining surfaces is wetted with an adhesive layer having incorporated and/or attached solids particles, and the remaining joining gap is filled with an inorganic and/or organic filler material.

Abstract: Disclosed is a method for determining the degree to which parts, especially parts that are exposed to loads (11) which change over time, are damaged. According to the invention, the part (10) is actively excited (20). A sector of the surface of the excited part (10) is recorded by means of a thermographic apparatus (30) which records also small cracks, microcracks (15), and microplastic zones having a length or size of less than 2 mm on the surface of the part (10). The thermographic apparatus (30) feeds the recorded images with the small cracks, microcracks (15), and microplastic zones to an evaluation unit (40). The evaluation unit (40) systematically evaluates the represented distribution of the small cracks, microcracks (15), and microplastic zones according to a predefined process. The degree to which the part (10) has been damaged is determined from the evaluated data of the distribution of the small cracks, microcracks (15), and microplastic zones.
