Abstract
The goal of a structural health monitoring system is to implement processes to detect and characterize damages in engineering structures. These systems may use many different physical phenomena to detect and characterize damages. One of these phenomena is elastic wave propagation in thin plate like structures, known as Lamb wave propagation. To develop a SHM (structural health monitoring) system based on Lamb wave propagation we first need to understand how Lamb waves interact with different damage types. The aim of this study is to develop an understanding of how Lamb waves interact with different types of damages using analytical modeling and FEM. The goal is to identify and characterize a surface breaking crack by understanding its effect on Lamb waves scattered from it. doi: 10.12783/SHM2015/75
