The testing of spring prototypes was conducted on an Intron tensile testing machine. From the data collected the csv files were uploaded into MATLAB for analysis. The maximum force for each spring was extracted and the force curves were plotted against each other to compare their behavior as they deformed.

To determine an estimated maximum force of the springs from FEA simulations this code was made to calculate it and took inconsideration the spring's cross section as well.

This code will extract a stress strain graph from the dogbone test and allowed analysis of material properties.
