Mechanical Engineering Department Holds Discussion for Master’s Thesis on “Defect Detection in Composite Plates through Integrated Computational and Experimental Vibration Analysis”
A Master’s thesis titled “Defect Detection in Composite Plates through Integrated Computational and Experimental Vibration Analysis” was held for discussion at the Mechanical Engineering Department of the University of Technology. The thesis, presented by Omar Nabhan Saleh, focused on detecting defects in composite plates using an integrated approach combining computational and experimental vibration analysis.
The research involved creating various sizes and locations of delamination defects using the hand lay-up method. Delamination between layers was introduced using strategically placed Teflon sheets. Vibration analyses revealed that delamination significantly reduces natural frequencies, with experimental results and finite element analysis (FEA) showing excellent agreement, maintaining error rates below 5.4%. Additionally, a comprehensive database of natural frequency changes due to delamination was developed using FEA, encompassing 160 different scenarios.
The discussion committee consisted of:
• Prof. Dr. Ibtihal Abdul-Razaq Mahmood (Chairperson)
• Assist. Prof. Dr. Ihsan A. Baqer (Member)
• Dr. Qaisar Aziz Amin (Member)
The thesis was supervised by Prof. Dr. Alaa Abdulhady Jaber and Assist. Prof. Dr. Rasha Mohammed Hussain.
