A comparative study of invariant-based hyperelastic models for silicone elastomers under biaxial deformation with the virtual fields method.

open access: yesJournal of The Mechanical Behavior of Biomedical Materials, 2022
Silicone elastomers have been widely used for biomedical applications. A variety of hyperelastic models have been proposed to describe this type of materials in the past few decades. The assessment of the quality of the proposed models is mostly based on

Calibration of a modified Johnson-Cook model using the Virtual Fields Method and a heterogeneous thermo-mechanical tensile test

open access: yesInternational Journal of Mechanical Sciences, 2021
Classical calibration procedures for phenomenological thermo-elasto-viscoplastic constitutive models usually involve a large number of tests to identify all the material parameters, leading to long experimental campaigns.
