摘要

Damage detection using Lamb waves is based on guided ultrasonic waves introduced to a structure at one pointrnand sensed at different location. Damage in a structure is identified by a change in the output signal. Previousrnstudies show that even simple excitation signals can lead to complex response signals. Therefore knowledgernand understanding of wave propagation can ease the interpretation of damage detection results. There existrnvarious modelling techniques for acousto-ultrasonic wave propagation. The paper reports an application ofrnthe local interaction approach. The focus of the analysis is on two-dimensional wave interactions with defectsrnin metallic structures. The method shows the potential for complex modelling of acousto-ultrasonic waves inrndamage detection applications.
