Abstract Scope |
Microstructure--property relationships are central to design of structural materials. Advances in computational methods made it possible to directly simulate bulk properties using 3D microstructure-based models. 3D representative volumes of microstructures required as input to these models are typically obtained either from 3D characterization experiments or digital reconstruction based on 2D microstructure information. In this work, we present a machine learning model that predicts bulk properties directly from 2D microstructural sections. The model is trained on a specially designed dataset that contained microstructure features quantifying 2D sections of diverse and synthetically generated 3D microstructures and their corresponding properties obtained from 3D simulations. Upon training, the model allows predicting properties from 2D sections (whose experimental acquisition is more accessible than 3D characterization) and without the need in additional computations (and underlying assumptions) involved in digital reconstruction of 3D microstructures. |
