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 is to be used for this purpose. The cracks in the tensile specimen that occur during tensile testing release elastic energy in the form of transient elastic waves, which can be detected using suitable sensors. This methodology is known as acoustic emission analysis (AEA) and provides information on the damage state of the tensile specimen. In addition to acoustic emission analysis, the tensile test will also be investigated using digital image correlation, allowing local resolution of specimen strain. The derived parameters from the applied measurement methods will be used to intervene in the control loop of the tensile testing machine. The novel control system is expected to allow a more accurate determination of material parameters.
