Quasi-static crushing of the S-shaped square tube Abaqus

The tube is made of milled steel. the cross section of the tube is square-like and the general shape of the tube is in form of S. compressive load is applied to the top of the tube causing that to be deformed

In this picture the results obtained from the abaqus software have been compared with experimental results

In this picture the diagram of force-displacement has been drawn

This project has been validated, which means that the results obtained from Abaqus software are similar to the results of the article. In other words, this project is based on the article
