The Introduction

A column has been modelled using 10 stacked torus. Each torus is inflatable and has air inside. The compressive load is applied on it. The finite element analysis has been performed using abaqus. Dynamic explicit procedure has been used to simulate the behaviour of the column under compression.

This tutorial gives a good insight of surface to surface interaction modelling, fluid cavity usage and constraints in abaqus.

The dimensions of torus is shown in Figure 1 below.

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 intended to give an insight of interaction and fluid cavity modelling. Some more analysis with different parameters may require to get more realistic results.
