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: overcome difficulties above, four measures are adopted. 1) Topology optimization model is established by independentcontinuous mapping (ICM) method. 2) Based on the von Mises strength theory, all elements’ stressis divided to classify into three cases. 4) A strategy based on strain energy is proposed to adopt ICMmethod with stress globalization, and the problems of the above mentioned three cases of load illnessfor local stresses constraints, and the problem of load illness can be solved well by the weighting method
