The project supports the thesis "SE signals of crack growth differ depending on the microfractographic crack growth behavior" by laboratory tests with different influencing parameters.

SE signals of crack growth differ depending on the microfractographic crack growth behaviour. This working hypothesis is to be substantiated in the research project on the industrial series production of springs by statistically planned laboratory tests with different influencing parameters. The development of suitable analysis chains in the plant-specific software should also enable the detection and unambiguous assignment of the in situ SE signals to material responses within the manufacturing process. The measured values obtained allow conclusions to be drawn about the damage mechanism, so that remedial measures can be defined and implemented in production directly and without further time-consuming or even destructive investigations. This would be of considerable technical benefit to interested SMEs.
