- Click on
Codeon the upper right corner, andDownload ZIP. - Put the
extrudion.batfile in the folder containing.TRAfiles. - Double click to run it.
Run this file in the folder containing .TRA files.
It will ask for surface_area in mm2 and then for initial_length, in mm.
It output the analysis.csv file containing all the results, as shown in the mathematical formula section of this page.
The plots for each files are stored in the plot folder in the same directory.
Stress = Force['N'] / (sample_area) * 10^3
returns the stress in kPa
Strain = ln( length['mm'] / initial length ['mm'] )
Young Modulus = slope of the best line fit with max slope for the curve
Intercept = the intercept of the previous fit
Yield Stress and Strain are the points of intersection for the Young modulus line shifted by 0.02 in the Strain and the data.
It needs Python 3.10 or greater. All other dependencies will be installed. If Python is needed install from here
