Abstract
In this paper, Lamb wave propagation in damaged composite laminates is simulated and validated using experimental data. First, a composite coupon fatigue testing setup is given and the corresponding lamb wave diagnosis signal is collected. Following this, a finite element model is developed to simulate the lamb wave propagation and parametric studies are performed to investigate the sensitivity of model paramters. Next, the damaged composite coupon is simulated using the above model, in which the effects of delamination and matrix crack on the lamb wave signal are investigated in detail. The simulation result is compared with the experimental testing observations for verification and validation. Finally, some conclusions and future works are drawn based on the proposed study.
