Analyzing a 2D Truss Using FEM

Assignment of “mechanics of materials II”. 2001 Winter

A MATLAB program is written in which users can define a 2D truss in 3way: keyboard, Input file, and mouse.

Run0_E

Entering path, the input file structure is shown.

Run File01

If data is chosen to be entered in command prompt, user can visually watch node locations. Joints are, also, visible during joint creation step.

Run02

Mechanical properties of each element can be defined separately.

Run03

Stress and Strain in all elements are shown in a table, and the deformed shape of the structure is compared visually to the original one.
