This lesson covers the advanced material of piezoelectricity and its application in smart structures. It delves into the concept of smart structures, which are composite laminated structures integrated with smart materials like piezoelectric materials, magnetostrictive materials, or shape memory alloys. The lesson explains how these structures control vibration, deflect, and perform other desired functions. It also discusses the application of smart structures in aerospace, naval structures, automobiles, and space technology. The lesson further explores the mathematical models for analyzing these structures, the advantages and disadvantages of smart structures, and the concept of hybrid laminates. It concludes with a detailed explanation of the development of governing equations for piezoelectric shell modeling.
