Smart Structures

ABOUT THE COURSE: This course will cover four different smart materials namely piezoelectric materials, shape memory alloys, electro and magneto rheological fluids. Materials properties of these materials and development of their constitutive relations will be discussed. Mechanics of fibre reinforced composite laminates will be introduced. Next, analysis of metallic as well as fibre composite structures fitted with these materials will covered. Analysis will involve both close form and approximate solutions of the respective governing equations. Development of codes for such analysis will also be discussed.INTENDED AUDIENCE: BE/ME/PhD student in Aerospace Egineering /Mechanical Engineering/ Civil Engineering/ Ocean Engineering and Naval Architecture and industry professionals from similar fieldsPREREQUISITES: Structural Analysis Dynamics and VibrationINDUSTRY SUPPORT: Industries that deal with aeropace, mechanical or civil structures.
