Multiscale Reduced Order Modeling of Complex Multi-Bay Structures
Abstract
This investigation focused on achieving quantum improvements in the reduced order modeling of structures undergoing large deformations especially those of future hypersonic vehicles. The present effort aimed at spanning a much broader ranges of scales than prior investigations had achieved, i.e. being able to capture the effects of localized geometrical defects (stress hot spots at the microscale level) but also to consider macroscale structures which are assemblies of panels themselves considered here as the microscale. These objectives were successfully accomplished through four separate investigations: (1) The micro-meso upscaling process, i.e. how to account for microscale features in nonlinear reduced order models of mesoscale models; (2) The reduced order modeling of mesoscale structures with difficult features such as curved structures with snap-through motions and cantilevered ones; (3) The extension of the mesoscale strategies for the construction of monolithic (single scale) reduced order models of macroscale structures, and (4) The meso-macro upscaling process.
