Where Humpty Dumpty Breaks: Geometry-Driven Fracture in Ellipsoidal Shells
Naoki Sekiya, Yuri Akiba, Kai Kageyama +3
Fracture networks are ubiquitous in nature, spanning scales from millimeter-sized cracks in botanical peels to hundred-kilometer-long lineae on planetary satellites. The propagatio…
Empirical rule of fruit rind fragmentation in muskmelon netting
Yuri Akiba, Akari Ishibashi, Motohiro Sato +1
The suberized netting tissue on the surface of muskmelons is a remnant of the rind fragmentation caused by the mechanical imbalance between the expanding flesh meat and the solidif…
Universal fluctuation of polygonal crack geometry in solidified lava
Yuri Akiba, Aika Takashima, Hiroyuki Shima
Outcrops of columnar joints made of solidified lava flows are often covered by semi-ordered polygonal cracks. The polygon diameters are fairly uniform at each outcrop, but their sh…
Flow velocity-dependent transition of anisotropic crack patterns in CaCO pastes
Yuri Akiba, Hiroyuki Shima
We investigate the desiccation crack patterns on the surface of a drying paste made of calcium carbonate (CaCO) powder and distilled water. Forced vibration of the CaCO pas…
Morphometric analysis of polygonal cracking patterns in desiccated starch slurries
Yuri Akiba, Jun Magome, Hiroshi Kobayashi +1
We investigate the geometry of two-dimensional polygonal cracking that forms on the air-exposed surface of dried starch slurries. Two different kinds of starches, made from potato…
