Abstract This work deals with the parameter identification of invariant-based hyperelastic materials using the virtual
fields method (VFM). Combined with the full-field deformation data obtained from the digital image
correlation (DIC), VFM has been utilized to characterize the mechanical properties of hyperelastic materials
[1]. In the conventional formulation of the VFM, the calculation of the internal virtual work (IVW) needs to
obtain the stress and conjugate virtual strains, which requires a lot of calculation and derivation work. In
this paper, the VFM is reformulated by calculating the IVW through the variation of elastic energy, which is More >
