For ecological and economic reasons, plastics are increasingly being used in the automotive sector. Compared to metallic materials, these offer a better ratio of mechanical load capacity in relation to the mass of the component. Further advantages are their insensitivity to media such as weak inorganic acids and alkalis. In contrast to other materials, however, polymer materials have a tendency to stress corrosion cracking under mechanical stress in the presence of organic media.
The aim of this work is the construction of a measuring set-up to measure the time after which a plastic substrate, which is mechanically and simultaneously medially loaded, fails. For this purpose there are different possibilities available, which are to be constructed and examined for practicability. For crack detection, an arduino-based measuring system consisting of various sensors is available, which is to be constructed and evaluated within the scope of the work.
