摘要
•Stochastic scale-bridging is performed between the meso and macroscale, with continuous information flow from macroscale experimental data.•Uncertainty in microstructure and constituent behavior is considered jointly in inferring continuum damage model parameters directly from higher length-scale experiments.•Mesoscale constituent model uncertainty is propagated towards probabilistic microstructure-sensitive predictions.
