MATLAB implementation of Material Knowledge System for predicting stress--strain responses in non-linear two-phase composites as presented in Latypov et al., 2018.
predict_response -- example script showing how to use the calibrated linkages for prediction of responses (effective strength and strain rate partitioning) for two-phase microstructure(s)
predict_ss_linear -- example script showing how to use the calibrated linkages for prediction of stress--strain curves of composites with phases exhibiting linear strain hardening behavior
predict_ss_power -- example script showing how to use the calibrated linkages for prediction of stress--strain curves of composites with phases exhibiting power-law strain hardening behavior
data\linkages.mat -- MATLAB file containing calibrated linkages (i.e., polynomial coefficients)
data\calibration.mat -- MATLAB file containing ensemble of microstructures used for calibration as well as their 2-point statistics and principal component basis needed for using the calibrated linkages
data\ms_examples.mat -- MATLAB file containing 38 example microstructures (different from calibration set) that can be used for testing the models
vendor -- folder with dependencies needed to use the prediction functions.
