Innovative materials are improving the function of components, machines and systems, and expanding their areas of application. This is particularly evident in relatively new industries such as lightweight construction. However, components based on new materials must also be reassessed in order to ensure the strength and safety of the final product. To evaluate the mechanical properties and service life, investigators turn to methods such as fatigue tests under cyclic loading. But this measurement takes time, with the test typically lasting anywhere from several hours to several days. Now scientists at Fraunhofer IPM and Fraunhofer IWM have succeeded in reducing test times for non-contact, strain-controlled fatigue tests by a factor of ten.
