建立了一个半解析有限元模型，研究了平面导波斜入射到直几何特征上的散射问题。该模型首先被用来调查的反射的S0模式从一个自由的边缘和结果相比，体波从一个自由的边界反射。然后，利用该模型预测S0模态通过粘贴加强筋的传播。所得到的结果与实验测量非常一致。
A semi‐analytical finite element model is developed to study the scattering of plane guided waves obliquely incident on a straight geometric feature. The model is first used to investigate the reflection of the S0 mode from a free edge and the results are compared to those of bulk waves reflecting from a free boundary. The model is then used to predict the transmission of the S0 mode past an adhesively‐bonded stiffener. The results obtained are in excellent agreement with experimental measurements.
