This research presents an experimental investigation of a planar robotic swimmer with a passive elastic joint. Bio-inspired robotic swimmers have been widely studied as a means of understanding aquatic locomotion and developing efficient underwater robotic systems. Previous studies investigated fully...
High-performance amorphous polymers, such as Polyetherimide (PEI / Ultem 1000), are increasingly vital in demanding aerospace and structural mechanical applications. However, predicting their plastic failure under multiaxial stress states remains a critical design challenge, as classical metal-based criteria fail to...
Data-driven constitutive modeling has the potential to redefine material mechanics, yet its progress is fundamentally bottlenecked by the difficulty of experimentally capturing rich, multiaxial stress–strain datasets. Conventional methods like Digital Image Correlation (DIC) provide full-field total strain distributions but lack...
