Identification of the mechanical behaviour of foot tendons [English translation]

The aim of the work is to analyze and study the mechanical behaviour of foot tendons through uniaxial traction and stress relaxation tests, with particular attention on the tendons of the ankle (achilles tendon, peroneal tendons, tibialis tendons). All the tissues avaliable came from amputations.
The first part of the work included the laboratory study, with the execution of the experimental tests at the Biomomentum. From the collected data it was possible to elaborate the values using the Matlab software, in order to derive the stress-strain curves for each tendon. The next step was to execute the fit of the curves with the exponential model, from which the parameters for the confrontation of the results came.
In conclusion, the work included the Abaqus simulation of the mechanical behaviour of the achilles tendon uder uniaxial traction, thus to have a further mean of confrontation between the f.e.m. model and the experimental results from the laboratory tests.
