Three phenomenological hyperelastic material model formulations (Ogden, Polynomial, Yeoh) were preselected from literature and had to be fitted to closely match previously measured stress-stretch curves from uni-axial compression/tension as well as simple shear measurements. Information on the theoretical background can be found in [1] and [2]. The scripts were initially created with Scilab 5.4.1 and revised with Scilab 5.5.2. Feedback on the scripts is welcome.
