Abstract: A method for determining constitutive parameters of a subject material includes collecting a force sensor output from a force sensor unit for measuring reactive forces applied to a deformation tool from a subject material travelling in a predefined direction relative to the deformation tool, collecting an image sequence output from a camera unit depicting a deformation zone formed between the deformation tool and the subject material as the subject material is plastically deformed by the deformation tool, and estimating a constitutive parameter of the subject material based on the force sensor output and the image sequence output.
