Abstract

In this paper, a set of expressions for the characterization of circular cell honeycombs as micropolar elastic solids is derived using a combination of non-dimensional analysis and numerical analysis. Closed-form expressions for the four in-plane (i.e. the plane normal to the generators of the cells) micropolar compliances are derived in terms of the cell size, cell thickness and the linear elastic properties of the cell wall material. Independent analyses are conducted to verify the accuracy of the derived constants.
