Abstract

This project aim is to detect the damage detection on aluminum material by using centered finite difference method. The primary purpose of making this project is to detect the depth crack size from 0.5 mm, 1.0 mm and 2.5 mm on a specimen. There are consists of multiple steps that can be used to detect depth of crack size by calculating using damaged mode shape curvature, undamaged mode shape curvature, damage index and damage estimate reliability. Furthermore, Microsoft Excel and LabVIEW software are used to record the data, generate graph for damage estimate reliability and help with numerical simulation resolution
