The invention relates to a method for evaluating measured values for identifying defects due to material fatigue on aircraft parts during which extension sensors (6) are placed at critical locations of an aircraft (1) or on parts thereof. The measured values of these sensors are, at different loading states, recorded, amplified and stored by a number of measuring circuits, and based on these measured values, an evaluation device (9) derives, signals or indicates a material fatigue by comparing actual measured values with previous measured values. The evaluation method is characterized in that the critical aircraft parts (1) are subjected to a multitude of predetermined loading states by a multitude of loading elements (3), and that the extension caused thereby is detected by a multitude of measuring circuits, and the evaluation device (9) forms, for at least each loading state and each measuring circuit, an associated reference value and a permissible limit value range, which is subsequently associated with the actual measured values so that the exceeding of the limit value range depicts an appearance of material fatigue. |
