Enhancing Durability and Mobility through Optimized Plasticity

Abstract

U.S. Air Force platforms that involve structural components are designed to withstand a variety of static and cyclic loading conditions where thermal management is simultaneously required. Current designs for metallic and multi-material hybrid structures based on elastic (yield-limited) analysis lead to bulky structures that are sub-optimal for weight-critical applications. These applications range from hypersonic thermal protection systems to stiffeners for exhaust wash structures on embedded engine aircraft with optimized payload capabilities. This project sought to overcome these limitations by providing experimentally validated inelastic design guides and parametric/topology optimization tools. In this way, inherent material and structural capabilities are fully exploited in design methodologies.
