ABOUT THE COURSE: The objective of the course is to learn the principles of solid and structural mechanics that can be used to design and analyze aerospace structures. Aerospace structural analysis is a fundamental course dealing with analysis of thin walled aircraft structures required for design of aerospace vehicles. The course primarily discusses analysis of thin-walled aircraft structures under torsion, shear and bending loads from the concepts of theory of elasticity. It also discusses stability and buckling of aircraft structures.INTENDED AUDIENCE: Undergraduate/Post-Graduate Students and Professionals working in Aerospace IndustriesPREREQUISITES: Third year undergraduate students with prior knowledge of solid mechanics/strength of material can successfully do this courseINDUSTRY SUPPORT: Any aerospace industries like Airbus/Boeing/GE/L&T/Relevant DRDO/CSIR Labs.
