Universality in the velocity jump in the crack propagation observed for food-wrapping films for daily use
Aoi Nohara, Ko Okumura
The velocity jump found in the crack propagation for rubbers has been a powerful tool for developing tough rubber materials. Although it is suggested by a theory that the jump coul…

Continuous generation of confined bubbles: viscous effect on the gravito-capillary pinch off
Haruka Hitomi, Ko Okumura
We investigate continuous generation of bubbles from a bath of air in viscous liquid in a confined geometry. In our original setup, bubbles are spontaneously generated by virtue of…

Universality in the mechanics of soft Kirigami
Yukino Kako, Ko Okumura
Recently, simple scaling laws concerning the mechanical response and mechanical transition of Kirigami have been revealed through agreement between theory and experiment for kiriga…
