Topic: Piezoelectric Sensor for Structure Health Monitoring (SHM) Analysis using ANSYS mechanical (FEM) and Comparison with Matlab Simulation.
Abstract: Structure health monitoring (SHM) is emerging as a vital and important tool for engineers to manage and improve the safety of all kind of structures. Human lives are being endangered everyday with structure failures resulting from aging buildings or faulty structures. With the importance of SHM growing from time to time, many people have done research on different methods for structure health monitoring using the advancement of technology available nowadays. A lot of methods are being developed and compared before being implemented successfully in the construction and mechanical industry.
In this research, a method of SHM which is using piezoelectric sensors that can generates Lamb wave for detecting structure damages or cracking damages is being analysed. Ansys which is a powerful Finite Element Method software is being used to analyse the effectiveness of this Finite Element Analysis method for SHM using piezoelectric sensor. To measure the effectiveness of this method, the results obtained will be compared with results obtained from Matlab simulation, while other fellow research group mate will compare with experimental result. Aluminium plate with two piezoelectric which is acting as a sensor and actuator will be used for this research. The feasibility of using Ansys for Finite Element Analysis to analyse piezoelectric sensor for SHM will be tested which may prove to be a useful tool for future Finite Element applications.
