Numerical and experimental framework for bending elasticity of highly flexible slender structures
Shunsuke Nomura, Satsuki Shibuya, Isamu Hashiguchi +2
The paper presents a hybrid material point method framework that combines finite element and finite difference techniques to simulate three‑point bending tests of highly flexible s…
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…
Analytical Expression for Fracture Profile in Viscoelastic Crack Propagation
Hokuto Nagatakiya, Naoyuki Sakumichi, Shunsuke Kobayashi +1
We derive an analytical expression for the strain field during steady-state crack propagation in viscoelastic solids described by the standard linear solid (Zener) model. This expr…
Revisiting Volterra defects: Geometrical relation between edge dislocations and wedge disclinations
Shunsuke Kobayashi, Katsumi Takemasa, Ryuichi Tarumi
This study presents a comprehensive mathematical model for Volterra defects and explores their relations using differential geometry on Riemann--Cartan manifolds. Following the sta…
Snap and Jump: How Elastic Shells Pop Out
Takara Abe, Isamu Hashiguchi, Yukitake Nakahara +5
Grip, walk, crawl, and jump. Soft robots are integrated functional structures composed of compliant mechanisms, whose activity spans various industrial applications such as surgery…
Curling morphology of knitted fabrics: Structure and Mechanics
Kotone Tajiri, Riki Murakami, Shunsuke Kobayashi +2
Knitted fabrics are two-dimensional-like structures formed by stitching one-dimensional yarn into three-dimensional curves. Plain stitch or stockinette stitch, one of the most fund…
