Abstract  This paper presents the topology optimization design of structures composed of plane stress elements. The authors\' proposed method of topology optimization by virtual laminated element is based on the Evolutionary Structural Optimization (ESO) method of linear elasticity, but dose not require formation of as many elements as the conventional ESO method. The presented method has the important feature of reforming the stiffness matrix in generating optimum topology. Calculation results showed that this algorithm is simple and effective and can be applied for topology optimization of structures.

Key words： virtual laminated element      evolutionary structural optimization      topology optimization      layer      segment      block
