A fellow engineer has recorded raw stress-strain data (elongation vs. force) for several samples. Your role is to develop a MATLAB program to simplify the analysis of the many samples available and compare the results. He has provided you with 4 samples of data. The samples include HIPS, Nylon6, ABS, and Polypropylene plastics. The samples were in the form of standard 'dog bone' formats with the following characteristics. As well, a video must be made of running the projects and brief explanation with having the collaborators. The .m file must be uploaded in addition to a word file of plots and results. Specify the portion of the contribution for each group member. Table 1: Material Description Material HIPS Nylon6 ABS Cross-sectional Area (mm^2) 2.482 2.482 2.482 2.482 Diameter (mm) 1.7777 1.7777 1.7777 1.7777 Gauge Length (mm) 18 18 18 18 Polypropylene The code must ask for the cross-sectional area, diameter, and gauge length. (i.e. The code must be interactive. When the code is ran, it should ask about the data path/folder/address, it should say "Is the cross-sectional area circular? [Y/N]" then be followed by several interactive questions.) Expectations are to provide: Elongation Curves (Position vs. Load), Stress Strain Curves (Strain vs Stress), Modulus of Elasticity, Ultimate Stress, and Fracture for each material. Plot elongation curves and Stress Strain curves on the same plot so they can be readily compared. Include legends. The MATLAB code should be able to be run for each dataset with output presented for easy understanding of the results in the Engineering Analysis Format. The code must have comments for every line explaining what is going on.
