Relaxation tests. (a) Load relaxation in continuous black line corresponds to strain step of 25%. Red, green, and blue continuous lines are the measured relaxations using a step strain of 50%. Both strains are also applied to the estimated models and the values are plotted in dashed-dotted lines with the same color code. (b) shows the time evolution of the absolute error between the experimental curves and models fitting curves in logarithmic scale.
