CompressAnalysis.m reads an Excel file containing Load [N] vs. Relative Displacement [mm] values obtained from compression of a cylindrical gel (with given height and diameter [mm]) until failure using a mechanical tester (like an Instron machine). After analysis, compressive modulus, yield, and ultimate stress and strain values are computed, results plotted with animation, and a new Excel file is created containing the results.
