Fig. 2: Partition of experimentally measured NMC particles.
From: Stochastic 3D reconstruction of cracked polycrystalline NMC particles using 2D SEM data

Segmented NMC particles together with their skeletons (yellow), where the skeleton segment of the longest crack is highlighted in red. The particle on the left-hand side belongs to \({\mathcal{G}}_{\rm{short}}\), consisting of predominantly short cracks, while the particle on the right-hand side belongs to \({{\mathcal{G}}}_{{\rm{long}}}\), exhibiting long cracks.
