In the topology optimization analysis of continuum, the checkerboards, that is the fomation of regions of alternating solid and void elements ordered in a checkerboard-like fashion, often appear in the optimum solutions. In this paper, a nodeless hybrid element is proposed and this element is applied to the topology optimization analysis of continuum in order to solve the checkerboards problem. The proposed hybrid element is fomulated based on the idea of nodeless element proposed by Kawai et al. and the stress assumed element proposed by Sekiguchi and Kikuchi. The homogenization design method is used for the topology optimization analysis of continuum. Some examples of two-dimensional problems are shown to demonstrate the effectiveness of the proposed element in the topology optimization analysis of continuum.
