Comporative study of polydimethylsiloxane (PDMS) for prediction of hyperelastic properties: application to silicone-rubber and soft tissues

Abstract

The correct modelling of constitutive laws is of critical importance for the analysis of mechanical behaviour of solids and structures. Hyperelastic models depend on sets of variables that must be obtained experimentally. In this study the authors use a computational/experimental scheme, for the study of the nonlinear mechanical behaviour of biological soft tissues under uniaxial tension. The material constants for a different hyperelastic materials models are obtained via inverse methods. This study intents also to select which material models (or model types), the authors will employ in future works, for the analysis of human soft biological tissues.
