INFLUENCE OF COMPOSITE PATCH SIZE AND SHAPE ON LAMB WAVE DETECTION OF ALUMINUM PLATE REPAIR STRUCTURE
摘要
Abstract
In order to study the influence of composite patch size and shape on lamb wave detection of aluminum plate repair structure,the structure models including piezoelectric transducers (PZTs) with the piezoelectric and inverse piezoelectric effect,aluminum plate,composite laminate patch and adhesive layer were established by means of ANSYS software.The lamb wave signal was excited and received in the models.Tests were used to verify the correctness of the model.The influence of damage on the propagation characteristics of Lamb wave in the structure was studied.The damage detection of the structure with composite patch was simulated to study the effect of different size and shape patches repairing the 8rmm hole on the propagation characteristics.The simulation results of circular,square and rhombus patches show that different shapes have different effects on A0 and S0 wave packets.Rhombus patches of different sizes are also different for A0 and S0 wave packets.关键词
