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: difficulties above, four measures are adopted. 1) Topology optimization model is established by independent continuousmapping (ICM) method. 2) Based on the von Mises strength theory, all elements’ stress constraintsdivided to classify into three cases. 4) A strategy based on strain energy is proposed to adopt ICM methodfor local stresses constraints, and the problem of load illness can be solved well by the weighting method
