Element-dependent buckling loads of stiffened panels under cantilevered shear
Lifeng Wang, Zhongli Qiu, Xuanhao Cheng +4
The linearized buckling load of a stiffened panel depends on the stress stiffness its shell element assembles. We read it from exported operators against three truncations of one s…

Overlap-free multi-material topology optimization for minimum compliance in two and three dimensions by level-set-based negative-mapping interpolation
Dong Wang, Qianglin Ran, Xuanliang Wang +3
Gray elements and material overlaps at the interfaces limit density-based multi-material topology optimization. This article extends the level set-based negative-mapping interpolat…
