Tapered-spring finite element models and experimental results

Input and output files for Abaqus CAE finite element models, and experimental moment-rotation results, discussed in "Fold propagation in tapered-springs: Part I" and "Fold propagation in tapered-springs: Part II", Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences. Input files (.py) should be run as scripts in Abaqus CAE. Experimental data csv provides angles in degrees and moments in Nm. M1 corresponds to the torque gauge at the left end of the spring, and M2 at the right end.
