Abstract
The inplane elastic properties of perfectly circular and elliptic cell hone ycombs are derived through an analytical method and validated numerically. In the case of perfectly circular cell hexagonally packed honeycomb, the in plane elastic properties are shown to be isotropic. However, a departure fr om circularity of the cells leading to cell ellipticity results in the inpl ane properties becoming orthotropic. The orthotropic elastic constants are also derived analytically and validated numerically.
