Project Description:

The aim of the project is to develop a new type of adaptive control for a tensile testing machine. A sensor fusion concept based on non-destructive testing methods will be used for this purpose. The cracks that occur in the tensile specimen during the test release elastic energy in the form of transient elastic waves, which can be detected using suitable sensors. This method, known as acoustic emission analysis (SEA), provides information about the damage state of the specimen. In addition to acoustic emission analysis, the tensile test will also be examined using digital image correlation, which enables local resolution of the sample strain. The parameters derived from these measurement methods will be applied to intervene in the control loop of the tensile testing machine. The new type of control should enable a more precise determination of material parameters.
