Bending Analysis of Composite Cylindrical Shell — Lesson 4

This lesson covers the bending analysis of a composite cylindrical shell using Abaqus software. The lesson is led by Shranish Kar, a research scholar at the Smart Structures and Materials Lab, IIT Guwahati. The lesson begins with the problem of finding the three-dimensional stresses and displacements of cylindrical shells made of laminated composites under specific pressure and boundary conditions. The lesson then proceeds to demonstrate how to create a model, set work directories, dimension surfaces, create plies, set material properties, and assign sections. The lesson also covers how to set up a static analysis, apply loads, set boundary conditions, and mesh the part. Finally, the lesson concludes with how to analyze the results, visualize the results, and compare them with an exact solution.
