Simulation and Experiment of Impact Damages in Carbon Fiber Reinforced Plastic Using Pulsed Eddy Current Testing
摘要
Abstract
In order to evaluate impact damage of carbon fiber reinforced plastic(CFRP),the method of PEC based on magnetic field of y component is proposed. The influence of conductivity differences on the eddy current magnetic field is analyzed by finite simulation. The simulation results are demonstrated by experiments using the method of wavelet packet energy analysis. Simulation and experimental results show that the method of PEC based on magnetic field of y component can effectively identify defect caused by impact energy,and characterize the damages caused by different impact energy.关键词
