From: Tendons from kangaroo rats are exceptionally strong and tough

Mean stress-strain curves of each tendon. Mean stress-strain curves of PL (solid) and GAS (dashed) tendons from k-rat (red) and rat (blue) were obtained by fitting 3rd order polynomial curves (R-squares > 0.9) to average stresses over the range of strains indicated in the figure for all 10 samples of each tendon type.
