HCA Approach to Topography Design Optimization of a Structure for Fluid Structure Interaction (original) (raw)

This work explores a Hybrid Cellular Automaton (HCA) approach for optimizing the shape of aluminum thin-walled structures with a focus on blast mitigation. The primary goal is to minimize kinetic energy transferred from blast events to target structures by considering fluid-structure interaction. The proposed method integrates an Arbitrary Lagrange-Eulerian fluid-structure interaction finite element analysis model with a tailored HCA methodology, resulting in intricate shape designs that improve pressure response properties while demonstrating computational efficiency. Applications of the approach in scenarios of surface and buried detonations demonstrate a significant reduction in peak pressure and impulse on the target.
