摘要: 提出了一种基于超声Lamb波的双曲线定位方法，实现了复合材料板状结构的损伤定位。相比于椭圆定位方法，双曲线定位具有无需材料参数信息、不涉及频散关系以及不受材料各向异性影响的优点，可以较好地应用于板状复合材料的损伤检测中。

Abstract: Hyperbolic location method based on ultrasonic Lamb wave is proposed in this paper, the damage location of composite plate structure is realized. Compared with ellipse location method, hyperbolic location method has the advantages of needing no material parameter information, no frequency dispersion relation and no influence of anisotropy. It can be better applied to damage detection of composite laminates.
