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 concise and easier to… More >
