ISAZA, JÉSICA; MARIAKA, ISABELA  and  RAMIREZ, JUAN. CHARACTERIZATION OF MECHANICAL PROPERTIES BY FINITE ELEMENT METHOD INVERSE ANALYSIS COMBINED WITH INDENTATION TEST. Dyna rev.fac.nac.minas [online]. 2013, vol.80, n.179, pp.126-133. ISSN 0012-7353.

A method is proposed to determine the mechanical properties of materials by the use of the indentation tests. It also allows to determine the mechanical parameters that control the material mechanical response by combining experimental results with a numerical finite elements model. The first results presented in this study correspond to a simplified numerical modeling of silicone rubber. The rubber was assumed as an one-layer material with an isotropic linear elastic mechanical behavior. The method was validated analytically; and this analysis, specially the method, will be extended to biological multilayer models in further studies.

Keywords : Finite element method; inverse analysis; mechanical properties; indentation test; silicone rubber.
