Abstract
We present a microstructure and work hardening sensitive reduced-order model using random forest regression for predicting damage initiation in dual-phase (DP) steels. The ductile damage behavior of banded and non-banded DP steels is evaluated for various degrees of ferrite hardening. The banded microstructures show a superior damage resistance which is further improved by ferrite hardening. A general framework to rank the severity of damage initiation in various classes using a statistical fitting procedure is introduced. The regression-based and statistical fitting-based models can successfully quantify the damage initiation and group the various classes into three major clusters. The proposed framework is a step toward developing more effective and invertible reduced-order structure–property correlations
