Theory of Composite Shells

Indian Institute of Technology Guwahati and NPTEL via Swayam


Like beams and plates, shells are the functional element of structural engineering.At research level, a large group of researches work in the field of bending, free vibration, buckling and post buckling analysis of shells made of composites, sandwiches and advance material. In this course,basic concept of doubly curved surfaces will be developed and governing equation will be developed.This will help the participants to develop the shell equations as per their requirement.Bending,free vibration and buckling of shell will be explained.Atutorial using ABAQUS will also be conducted.
