Structural Testing And Analysis Of Hybrid Composite/Metal Joints For High-Speed Marine Structures, Jean Paul Kabche
Structural Testing And Analysis Of Hybrid Composite/Metal Joints For High-Speed Marine Structures, Jean Paul Kabche
Electronic Theses and Dissertations
The implementation of composite materials in engineering applications has observed a rapid increase over the last few decades. The U.S. Navy currently has an objective to enhance its future naval capabilities by developing hull-forms with advanced materials, including composites. Speed can be increased by reduction in weight and by incorporating innovative shaping of the hull-form, which can potentially be achieved with composites. Any naval vessel using composite materials for structural components will require hybrid connections of some sort, where composite sections are joined to metallic sub-structures. Joints are critical regions in the design of hybrid systems, as failures typically occur …
Analysis And Structural Health Monitoring Of Composite Plates With Piezoelectric Sensors And Actuators, Richard C. Mewer
Analysis And Structural Health Monitoring Of Composite Plates With Piezoelectric Sensors And Actuators, Richard C. Mewer
Electronic Theses and Dissertations
Structural vibration suppression and health-monitoring have been the focus of intense research over the past decade, and piezoelectric actuators and sensors are particularly well suited to serve in this application. The first part is an analytical investigation into the cylindrical bending vibrations of piezoelectric composite plates. The second part is a fully experimental investigation into various vibration based structural health-monitoring techniques for bolted composites. The analytical solution consists of Fourier basis functions that satisfy the equations of motion and charge equation. The accuracy of the mechanical displacements, electric potential, and stresses are dependent on the number of terms in the …
