Abstract
Tendons may be temporarily or permanently damaged under conditions of excessive high-rate loading. It is important for surgery decisions to predict the intensity of tendons injures. It can be done by the determination and understanding of the mechanical response and the failure modes of tendons under loading. One of the important issues concerned with tendons is mechanical hysteresis, demonstrating the ability of the tendon to dissipate energy, which indicates that the muscular tension is not fully transmitted to the skeleton. The aim of the study was to determine mechanical hysteresis of porcine tendons model under cyclic loading in the quasi-static tensile test. Repeated ten loading-unloading cycles in the quasi-linear tensile test were made for three levels of the maximal load: 50 N, 100 N and 150 N. Three hysteresis loops for each level of load were registered (1st, 5th, 10th) and used for calculation the values of energy dissipation and mechanical hysteresis. The mean values of energy dissipation were 4.4 ±0.7 mJ, 19.7 ±3.7 mJ, 23.9 ±3.9 mJ for load levels 50, 100 and 150 N, respectively. Between fifth and tenth cycle for which the stabilization of the mechanical hysteresis was observed, its values were between 22 and 32%, what was about half of the hysteresis value for the first cycle. The influence of the applied loads on the values of both the energy of dissipation and the returned energy can be seen but the value of mechanical hysteresis is independent of load levels.
