Abstract

Structural load has significant effects on propagation of guided waves and therefore can increase the diagnostic uncertainty of the guided wave-based damage detection, which may cause the diagnostic error of damage. In order to mitigate the load effect, a load compensation method based on improved baseline reconstruction is developed in this study, which can compensate the phase of baseline signal to the phase of current signal. The effectiveness of the proposed method is validated by the static tensile test of aluminium panel and damage monitoring of composite T-joint under tensile load. The results show that the proposed method can effectively mitigate the load effect on the phase of guide wave signal, and detect the damage of composite T-joint under tensile load accurately.
