Measurements taken during a test must be reliable as well as durable or be present for the duration of the test. Where this is not possible, it is advisable to adopt methods that allow to anticipate in real time the fatigue failure of the instrumentation that represents, in the context of structural tests in the aeronautical field, the first cause of loss of measurement channels, in particular as regards measurements with strain gauges electric resistance. For this puprose the first step of my thesis was to study the feasability about the implementation of Goodmann\Gerber fatigue calculation in Catman® Enterprise\AP toestimate the life expectancy (in cycles) of strain gauges attached to test articles using a Stress-Life approach.
