Abstract: Buckling is a long studied mechanical process that has been tackled from a variety of theoretical and numerical methods over the past two and a half centuries. Modeling buckling behavior of complicated structures—especially new composite material(s) in an expeditious manner remains an open question, which becomes more important as architected and smart materials come into modern consideration. Despite much research, predicting buckling behavior of materials with complex structure and components, such as notched beams of non-homogeneous architected composites, remains non-trivial. The present disclosure addresses the above problem by applying artificial intelligence methods to model physical relationships directly from observational data.

Abstract: The present invention, in some aspects, provides compositions including a solution comprising a plurality of exfoliated silk microfibrils and/or exfoliated silk nanofibrils, wherein the micro- or nano-fibrils are characterized as having a substantially nematic structure, as well as methods for making and using the same.

Abstract: Materials-by-design is a new paradigm to develop novel high-performance materials. However, finding materials with superior properties is often computationally or experimentally intractable because of the astronomical number of combinations in design spaces. The disclosure is a novel AI-based approach, implemented in a game-theory based generative adversarial neural network (GAN), to bridge the gap between the physical performance and design space. A end-to-end deep learning model predicts physical fields like stress or strain directly from the material geometry and microstructure. The model reaches an astonishing accuracy not only for predicted field data but also for secondary predictions, such as average residual stress at R2˜0.96). Furthermore, the proposed approach offers extensibility by predicting complex materials behavior regardless of shapes, boundary conditions and geometrical hierarchy.
