This paper is focused on the identification of the in-plane elastic constants of a new design of auxetic (negative
Poisson’s ratio) honeycomb configuration with curved cell walls by using analytical and numerical homogeni-
zation techniques. The sensitivity of the elastic constants is determined against the various cell geometry pa-
rameters. Good agreement between the analytical and numerical simulations is observed. We show that the
specific curved wall honeycomb configuration proposed in this paper possesses a high in-plane shear compliance,
tailored anisotropy and the possibility of inducing a negative Poisson’s ratio behaviour in baseline honeycomb
configurations that would have otherwise positive in-plane Poisson’s ratios.
