The effects of static air and hydrostatic pressure on the vibration characteristics of thin clamped circular plates: A coupled fluid-structural analysis

This thesis investigates the vibration characteristics of thin clamped circular plates, focusing on two fluid-structure coupling problems: interaction with pressurised air and hydrostatic water cavities. Analytical, experimental, and finite element methods are used to explore the vibration dynamics, resonance frequencies, and system responses. Key findings include the effects of cavity pressure, coupling strength, and modal compositions. The study provides validated models and insights into these coupled systems, contributing to the understanding and design of similar structures. The research fills gaps in existing literature and offers a foundation for future fluid-structure interaction studies.
