Summary: The variational asymptotic method (VAM) is used to determine the equivalent elastic stiffness tensor of auxetic materials for the first time. The VAM allows rotational degrees-of-freedom of the structural elements without any assumptions. The homogenized response of the unit cells is fully anisotropic, with specific possible responses of orthotropy or transverse isotropy depending on the arrangement of structural elements. The predictions of the VAM-based method are validated using commercial finite element software and open literature, demonstrating its versatility and computational efficiency in describing auxetic metamaterials.
