Stress collectives

Stress collectives – for realistic fatigue tests

When it comes to the test forces that are to be introduced, many standards are based simply on sinusoidal stress with a constant amplitude and constant average. Real stress, however, generally demonstrates variable amplitudes and average values.

We will be happy to support you when it comes to measuring the relevant stress collective, processing existing measurement data (rainflow analysis) or creating synthetic collectives based on normally distributed stress, for example.
