Topology Optimization of Structure Based on Modified Balanjin Theory

  • Received Date: 13 Mar 2008

  • In order to seek a new structural optimization method with engineering practicability,the evolutionary structural optimization(ESO) was applied to the topology optimization of structures based on a stress level.Through modifying the Balanjin theory,the stress level of elements was measured by the ratio of ultimate uniaxial tension to compression stresses and the principal stresses of elements.As a result,an evolutionary structural optimization method based on the modified Balanjin theory was proposed.The numerical results show that the proposed method can be used for the topology optimization of 2-D and 3-D structures effectively.
