电磁感应方法具有低成本、易测量、无需接触等优势，适用于碳纤维复合材料（carbon fiber reinforced polymers, CFRP）的无损检测。仿真建立CFRP单向模型，确立裂纹缺陷，得到磁感应强度和涡流分布；依据CFRP特性建立各向异性模型进行求解，通过对携带被测区域信息的磁感应强度、涡流和检测线圈中感应电压的计算及分析，探究电磁感应检测方法对单层各向异性CFRP的缺陷定位能力。结果表明，该方法能够通过感应电压区分裂纹与无损的CFRP、定位裂纹的位置以及确定裂纹深度的变化趋势，对精确区分和定位CFRP的隐藏缺陷提供参考依据。

The electromagnetic induction method possesses several key advantages, including cost-effectiveness, ease of implementation, and non-contact operation. These attributes render it particularly well-suited for non-destructive testing of carbon fiber reinforced polymers (CFRP). A unidirectional model of CFRP with predefined cracks was developed to investigate the magnetic flux density and eddy current distribution. Based on the characteristics of CFRP, an anisotropic model was established to address the solution. The defect detection capability of electromagnetic induction method for single-layer anisotropic CFRP materials was evaluated through a comprehensive analysis. Magnetic flux density, eddy current distribution, and coil-induced voltage were systematically characterized to quantify material responses in the measured region. The results show that the method can effectively distinguish cracks from non-destructive CFRP based on induced voltage. This method is capable of identifying the location and depth trends of cracks, thereby providing a solid experimental foundation for accurately detecting and locating hidden defects in CFRP.
