Durability and Resilence of Hyperloop Infrastructure
Abstract: ABSTRACT: The Hyperloop is a revolutionary concept for high-speed ground transportation that involves passenger pods traveling through low-pressure tubes at near-supersonic speeds. Originally proposed by SpaceX in 2013, the concept aims to offer a cost-effective and faster alternative to conventional rail systems and short-haul air travel. This study addresses a critical component of the Hyperloop's success—structural durability. Key concerns include material fatigue due to repetitive high-speed movement, pressure fluctuations within …

Advanced Magnesium-Based Metallic GlassComposites for Biomedical Implant Applications: AMachine-Learning-Informed Approach
Abstract: Magnesium-based bulk metallic glasses (Mg-BMGs) combine strength, low density, and tunable degradability. Their amorphous matrix has a small plastic process zone. This zone is only about 4 μm wide. A small process zone keeps most glasses brittle. Adding a second phase is the best fix. This chapter extends Mg-BMGs to true composites. We call these Mg-based bulk metallic glass composites, or Mg- BMGCs. The chapter covers matrix engineering and interfacial …
