HYPERFIT

Multiple data-sets can be used for calibration of a single model. Up to 95 data-sets can be used mixing the same and different test protocols without any restraints.
Example: Treloar's data (uniaxial + biaxial) & Arruda-Boyce model:

Response of the constitutive model with known/specific parameters can be predicted.
Example: Holzapfel model & Uniaxial tension:

Stress-strain response of the currently solved model is displayed in a real time during the calibration process.
Example: Yeoh model with Mullins' effect (Ogden-Roxburgh model):

Short movie demonstrating all stages of a typical calibration process (from starting the application, reading the experimental data, setting the neccesary features and running the optimization process).
