Independent continuous and mapping method of structural topology optimization based on the global stress

Yunkang SUI, Jili FENG, Hongling YE, Xirong PENG,

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 2,   Pages 130-142 doi: 10.1007/s11465-010-0011-3

Abstract: because the former becomes a multiple objective based on compliance objective functions. 2) With local constraints, such as an elemental stress limit, the topology is more difficult to be solved than with global constraintscontinuous mapping (ICM) method. 2) Based on the von Mises strength theory, all elements’ stress constraintsexamples show that the topology path of transferring forces can be obtained more easily by substituting globalstrain energy constraints for local stresses constraints, and the problem of load illness can be solved
