Piezoelectric sensors are attached to the structure to make sense of changes in the structure. Changes in the material properties of the piezoelectric sensor and the attached structure are caused by changing environmental conditions. In this study, electromechanical impedance method (EMI) is proposed for in situ inspection of landing gears in service. Knowing that these structures serve at low-temperature conditions, the tests were conducted between −10 °C and −45 °C. The specimen and sensor were modeled using ANSYS® finite element program. The experimental and simulation results are very close. The temperature effect was compensated using Effective Frequency Shift (EFS) method and compensated/non-compensated situations were compared using different damage metrics. The genetic algorithm was used to solve the compensation algorithm.
