Abstract

An active damage detection method using Support Vector Machine (SVM) is proposed. The SVM is known as a powerful pattern recognition tool that can be applied to complicated classification problems. An active sensing diagnostic technique using PZT elements was adopted to characterize damages in bolted joints. Built-in PZTs were used to predict damages by using differences of Lamb wave signals recorded before and after damages. The wavelet transform was applied for a time-frequency analysis of the Lamb waves to characterize the feature vectors for feeding to SVMs. It can correctly estimate the location and the degree of damages. Applicability of proposed damage detection method was successfully demonstrated.
