Software produced by the research group is available for non-profit applications at no charge in exchange for citation of appropriate papers when results produced using it are published.
Two programs are needed to implement this software. CatchSix reads six phase-stepped photoelastic images previously recorded using image capture software and compresses them into a single file for processing. CoPA performs the photoelastic analysis using the data contained in the single file generated by CatchSix. You need to download both pieces of software in order to proceed with an analysis.
