Abstract

This research investigates how the complex geometry of crack fronts in brittle solids affects their toughness. Using optical microscopy on various transparent materials, the study finds a direct relationship between the critical strain energy needed to propagate a crack and the crack front's geodesic length, implying that geometric complexity enhances toughness. This finding challenges existing fracture mechanics theories and has implications for materials science and engineering.
