Rheometer, neural network and oscillatory shear (G′, G″) data

Rheology & AI

Developing rheolyzer, a Python package that combines physics-based models with machine learning to read small-amplitude oscillatory shear (SAOS) data and report entanglement, flow behavior and model-free viscoelastic quantities with stated uncertainties. Also drafting visco-PEGS, a concept-stage research proposal for using machine learning to infer contact-force histories from images of photoelastic particles.
