            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

Feedback on the scripts is welcome.

Dear Michael, 
I'm afraid the files are no longer present.
Could you upload them again in the new version ?
