Shape optimization and buckling analysis of novel two-way aluminum alloy latticed shells

The circumferential profile of cylinder, as a classic shape, has been widely adopted in single-layer latticed shells. Previous research into these structures primarily concentrated on their buckling behavior. In this work, novel two-way aluminum alloy cable-stiffened shell is proposed to explore shape optimization procedure such structure. addition, the behavior optimized and cylindrical shells are examined compared. adopts linear algorithm, which structural strain energy selected be objective. Buckling analyses also performed compare with shapes. comparisons show that load-carrying capacities clearly enhanced by optimizing results presented article anticipated aid engineers design an optimal shape.
