Experimental measurement of the characteristics of silicone MED 4550 for FEM simulation

Abstract eng:
The Laboratory of Human Biomechanics, CTU in Prague is engaged in development of spinal replacement, among others on the basis of silicone. The design of the new type of spinal replacement assumes the restoration of the physiological properties in spine segment especially its normal mobility. One of the methods to predicate the functional properties of these replacements is a computer simulation using Finite Element Method. The necessary condition for relevant simulation of polymer material is the determination of their material properties that are not readily available. From that reason was necessary to perform the experimental measurement of the silicone material characteristics. On basis of the measured characteristics it was possible to determine the material parameters for several description of the material that are implemented in the environment of Finite Element Method solver.
