ABOUT THE COURSE:This course focuses on the modeling of properties of fiber-reinforced plastic (FRP) composite plies and the analysis of laminates constructed from these plies. It begins with an introduction to FRP composites, including the material properties of their constituents, followed by an overview of fabrication processes.The course then delves into the micromechanics and macromechanics of composite plies. Subsequently, it covers the static, dynamic, and buckling analysis of laminates made from these plies. The analysis of failure mechanisms in plies and laminates, as well as sandwich composites, will also be explored. Additionally, the course includes the development of computational codes for these analyses.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 AnalysisDynamics and VibrationINDUSTRY SUPPORT: Companies and Research & Development Organizations from various sectors such as aerospace, wind energy, marine, mechanical, construction etc, Examples include:Indian Space Research Organization (ISRO), Defence Research & Development Organization (DRDO), Airbus, Boeing, General Electric (GE), General Motors (GM), Suzlon Energy, Siemens Energy, LM Wind Power, Garden Reach Shipbuilders and Engineers Ltd.
