CTL-A Multidisciplinary Approach Gets to the Root Cause

In the elastic strain range of a material’s mechanical properties, there is a direct correlation between the strain and the applied stress, Δσ. This alternative stress provides a measurement of the fatigue stresses on the component. Since the changing strain appeared to be periodic, we decided to analyze the strain gauge data in terms of a
