Abstract

This research delves into the characterization of the ultrasonic transmission coefficient pertaining to various types of bonding defects in Fiber-Reinforced Polymer (FRP)-bonded structures. Initially, an ultrasonic transmission coefficient calculation model for FRP-bonded structures in a water immersion environment is established. This model is used to analyze the variation in the ultrasonic transmission coefficient under different defect types, namely intact bonding, interfacial slip, and debonding defects. Subsequently, a frequency domain finite element analysis model of FRP-bonded structures with different defect types is constructed. The simulation validates the accuracy of the theoretical analysis results and concurrently analyzes the variation in the transmission signal when the defects alter. Lastly, an experimental platform for water immersion ultrasonic transmission measurement is set up. The transmission signals under different defect types are extracted through experiments and evaluated in conjunction with theoretical calculations to assess the types of bonding defects.

摘要

本研究深入探讨了纤维增强聚合物（FRP）粘结结构中各种类型粘结缺陷的超声传输系数特性。首先，建立了水浸环境下FRP粘结结构的超声传输系数计算模型。该模型用于分析不同缺陷类型（即完好粘结、界面滑移和脱粘缺陷）下超声传输系数的变化。随后，构建了具有不同缺陷类型的FRP粘结结构的频域有限元分析模型。该模拟验证了理论分析结果的准确性，同时分析了缺陷变化时传输信号的变化。最后，搭建了水浸超声传输测量实验平台。通过实验提取不同缺陷类型下的传输信号，并结合理论计算进行评估，以确定粘结缺陷的类型。
