Strain distribution along the sheet thickness is relatively not homogeneous. Sheet metal forming at room temperature will have both elastic and plastic deformation due to the metal characteristic of elastic-plastic. Springback is defined as geometrical deviation after the process. In sheet metal forming process, springback is one of the important problems.

This verification tool helps students when they implement finite element procedures to solve structural problems Involving FreeMat in the learning process provides a quick verification check for the finite element solution. The spreadsheet is the main learning tool for students to implement finite element procedures whereas FreeMat is used for verification purpose in programming approach and LISA provides a practical skill in using finite element package program. FreeMat, which is a programming based learning tool, is used together with other higher level learning tools Open/Libre Office Spreadsheet and LISA finite element analysis application package. This study presents a strategy of teaching structural line elements involving an open source computer-aided learning tool FreeMat integrated with another open source CALFEM finite element toolbox. One of the important objectives in teaching finite element method at introductory level is to bring students into the comprehension of finite element procedures.
