Additive Manufacturing (3D Printing) of Aerospace Materials and Structures
Additive Manufacturing (AM), commonly known as 3D printing, is an advanced manufacturing technology that constructs complex geometries by depositing materials layer by layer. This research direction primarily focuses on the numerical simulation of the AM process itself and the multi-scale correlation between the resulting microstructure and the mechanical properties of the fabricated parts. Process simulation serves as a key tool for predicting thermal history, residual stress, and deformation, aiding in the optimization of parameters to minimize defects. Furthermore, multi-scale simulation bridges the gap from atomic-scale microstructure (e.g., grain size, phase composition) to macroscopic mechanical performance (e.g., strength, toughness, fatigue life). This integrated approach is particularly valuable for aerospace engine applications. It enables the design of intricate lightweight structures and provides a scientific foundation for predicting and optimizing the performance of new high-temperature alloys and composites, thereby driving innovation in the design and manufacturing of high-performance engine components.
