Explicit Topology Optimization Design of Stiffened Plate Structures Based on the Moving Morphable Component (MMC) Method

This paper proposes an explicit method for topology optimization of stiffened plate structures. The present work is devoted to simultaneously optimizing stiffeners’ shape, size and layout by seeking the optimal geometry parameters a series moving morphable components (MMC). stiffeners with straight skeletons curved are considered enhance modeling capability current approach. All represented under Lagrangian-description framework in fully way, adaptive ground structure method, as well dynamically updated plate/shell elements, used obtain optimized designs more accurate analysis results. Compared existing works, proposed approach provides description structure. Thus, clear stiffener distribution smooth geometric boundary can be obtained. Several numerical examples provided, including stiffeners, hierarchical cutout, validate effectiveness applicability
