Abstract
The paper describes the possibility to adjust the sensitivity of a fatigue damage indicator with respect to the loads applied to the monitored components. It is shown that the optimum geometry of the indicator and its sensitivity can be achieved by the application of the finite elements stress-strain analysis. This extends application of the proposed indicator onto a large number of aircraft components even those carrying small loads and loaded by compression. This approach provides also the additional possibilities to use fatigue indicators for inspection of wide range of engineering structures.
