Abstract

High-performance composites with improved stiffness-to-weight and strength-to-weight ratios are transforming energy-efficient structures to mitigate further CO2 emissions for the benefit of society. Such structures need to be efficiently designed and optimized for material performance and structural durability. Integrated Computational Materials Engineering is an emerging branch of mechanics intended to transform the design and manufacturing paradigm of advanced structures, and drastically reduce engineering time and cost through computationally-driven approaches. This talk will describe a novel ICME framework developed to design and optimize a composite Y-joint for the Aurora Flight Sciences D8 aircraft. Emphasis is placed on linking modeling tools to predict material-structure-property relationships at multiple length scales spanning from atomistic to macro. This ICME framework includes molecular dynamics simulations, finite element analysis, continuum damage mechanics, and structural sizing to create a digital twin of the joint and predict its structural performance based on loading history and manufacturing conditions.
