TANGO: dataset, trained models, and code for graph neural operator prediction of polymer-network stress–strain curves

TANGO is a graph neural operator that predicts the full uniaxial stress–strain curve of a polymer network from its graph representation. Polymer strands and crosslinkers are nodes. Chemical bonds and entanglements are edges. Given a network graph and any strain value, TANGO returns the predicted stress, with aleatoric and epistemic uncertainty.
