Topological Optimization of Artificial Microstructure Strategies

Abstract

During this project as part of DARPA MCMA we aimed to develop and demonstrate a 3D microstructural architecture structure made from bulk metallic glass, 3DMGS, exhibiting a combination of ceramic-like high strength (>1000 MPa), metal-like high plasticity (>20%), and polymer like density (<2 g/cm3). We developed novel processing methods such as BMG sheet fabrication and BMG joining. Topological optimization has been used to identify optimized structures for the combination of properties.
