Tytuł: Evaluation of effect changing temperature on lamb-wave based structural health monitoring

Opis:

The purpose of this paper is to investigate the effect of temperature change on the Lamb wave-based SHM method. This study evaluates the Lamb wave method’s ability to detect damage to an AL2024-T3 sheet, assessed by a near-surface hole. Lamb waves are created via numerical simulation with the commercial Finite Element (FE) package ABAQUS. In this study, the Lamb wave-based SHM method using displacement responses is used. The results indicate that this method is able to detect a near-surface hole in the AL2024-T3 sheet as well as its location, with close approximation. Subsequently, the AL1100 sheet was investigated for changes in temperature from this method, which was evaluated over a temperature range of –200(°C) to 204(°C). The results show that temperature change in the range of –200(°C) to 93(°C) has no effect on the displacement responses. However, the graphs related to temperature change of more than 149(°C) do not overlap with the reference temperature. Hence, it has been concluded that Lamb waves can be used as an SHM method in the temperature range of –200(°C) to 93 (°C) without having to worry about the effects of temperature change on the results.
