摘要：

In　this　paper,　a　model　of　topology　optimization　for　the　lightest　plate　structures　with　linear　buckling　constraints　is　constructed　based　on　Independent,　Continuous　and　Mapping(ICM)　method.　Exponential　function　is　adopted　as　filtering　function　of　the　element　weight,　the　element　stiffness　matrix　and　the　element　geometric　stiffness　matrix.　Based　on　the　Taylor　expansion　and　the　filtering　function,　the　buckling　constraints　were　approximately　expressed　as　explicit　functions.　The　optimization　model　was　translated　into　a　dual　programming　and　solved　by　the　sequence　second-order　programming.　Two　numerical　examples　show　that　this　method　is　validity　and　efficient.　©　(2014)　Trans　Tech　Publications,　Switzerland.
