Abstract
This current study is considered as a continuation of previous research in which static and cyclic tests were performed in accordance with the ISO 10328 standard on trans-tibial sockets made from natural fiber in order to characterize their mechanical performance. The experimental findings of the fatigue test have revealed a viscoelastic behavior of the composite material of the tested socket. In addition, it has been proposed to model the fatigue test by the Burgers model since it better fits the experimental results presented by fatigue curves. Two main objectives are distinguished. The first one is to identify the parameters of the Burgers model; the second one is to evaluate the natural frequency of the bench structure: Socket, Artificial stump and Test device Assembly used to perform the mechanical tests. The natural frequency, which is deduced from an electro-mechanical analogy method, is then used to optimize the design of the test device.
