Effect of internal length scale on optimal topologies for Cosserat continua

Abstract

Micropolar field theory represents an extension of the classical Cauchy continuum theory. In this paper, a topology optimization procedure for maximum stiffness is applied to two dimensional structural elements described in terms of micropolar (Cosserat) solids. The role of the characteristic length of bending on the optimal configurations is highlighted in the applications. © 2006 Springer.
