Abstract
To investigate the relation between the Poisson's ratio of a re-entrant honeycomb structure by varying the micropolar material constants such as micropolar Young's modulus Em, micropolar Poisson's ratio Vm, characteristic length l, coupling factor N, and micropolar elastic constants in accordance with the micropolar elastic restrictions, a 2-D triangular finite element formulation including an extra degree of freedom was derived on the basis of Eringen's micropolar elasticity theory by using a linear triangular element. The effects on the structural Poisson's ratio of the honeycomb structure are studied in detail.
