Introduction

In this post/tutorial, I have discussed the finite element analysis of bending of air filled thin cylindrical shell. I have already discussed Buckling of closed thin inflatable cylindrical shell column filled with air under compressive load. The same model has been used here with a change of load.

I have provided simulation files also in Simulation files section below, so that you can grasp more clearly what has been demonstrated in this tutorial.

Load and boundary condition

The cylindrical shell is 1m in height and has radius 0.2m as shown in Figure 1(a). The bottom is pinned and a top is loaded with surface traction parallel to the top face as shown in Figure 1(b) below.

The following video demonstrate the procedure to apply traction load on the top of the shell and resubmit the analysis. I have used the model which I have prepared earlier for the tutorial – Buckling of closed thin inflatable cylindrical shell column filled with air.

Results

After waiting for some time we got the results. In the following video, I have discussed about the results.

Simulation files

The simulation file can be downloaded from here.

The instructions to use these files is given here.

It is very helpful because there may be things which may not be clear to you by just watching/following the video tutorials. So, you can download and play around with simulation files while watching/following tutorials.

Take away

This tutorial is aimed at demonstrating the procedure to apply surface traction in load module; and see and interpret the results in visualization module. You learn to change the font size of the viewport, set a limit for field output results.

The data and results may or may not be realistic because it aims to demonstrate certain things not to get a realistic results.

Please report/comment any error, suggestion or questions.

Thank you!
