From: Early prediction of macrocrack location in concrete, rocks and other granular composite materials
(Color online) Flow chart summarizing the 4-step data-driven analysis of energy and force transmission for early prediction of the ultimate macrocrack path \({\mathcal {C}}\). A prediction of \({\mathcal {C}}\) from each of the eight criteria is generated at each stage of loading \(\epsilon =1,2,\ldots ,m\). The path of least resistance to fracture, as given by the flow bottleneck for energy (Criterion 1), force ( Criterion 3), or their respective residuals (Criteria 2, 4), provides an early prediction of \({\mathcal {C}}\).
