Elastocapillary lifting and encapsulation of water by a triangular elastic film under gravity
Kyoko Shibata, Hana Kanda, Yoshimi Tanaka +1
We investigate the encapsulation of water by a thin elastic film as a minimal model of elastocapillary self-folding with fluid transport. An equilateral triangular polydimethylsilo…
What is the physical origin of the gradient flow structure of variational fracture models?
Masato Kimura, Takeshi Takaishi, Yoshimi Tanaka
We investigate a physical characterization of the gradient flow structure of variational fracture models for brittle materials: a Griffith-type fracture model and an irreversible f…
Gradient flow model of mode-III fracture in Maxwell-type viscoelastic materials
Yoshimi Tanaka, Takeshi Takaishi
We formulate a phase field crack growth model for mode III fracture in a Maxwell-type viscoelastic material. To describe viscoelastic relaxation, a field variable of viscously flow…
The gradient flow structure of an extended Maxwell viscoelastic model and a structure-preserving finite element scheme
Masato Kimura, Hirofumi Notsu, Yoshimi Tanaka +1
An extended Maxwell viscoelastic model with a relaxation parameter is studied from mathematical and numerical points of view. It is shown that the model has a gradient flow propert…
Bouncing gel balls: impact of soft gels onto rigid surface
Yoshimi Tanaka, Yoshihiro Yamazaki, Ko Okumura
After thrown onto a solid substrate, very soft spherical gels bounce repeatedly. Separate rheological measurements suggest that these balls can be treated as nearly elastic. The He…
Fracture energy of gels
Yoshimi Tanaka, Koji Fukao, Yoshihisa Miyamoto
To clarify effects of crack speed and cross-link density on fracture energy of acrylamide gels, we evaluated the roughness of the fracture surface and measured the fracture energy…
Discontinuous Crack Fronts of Three-Dimensional Fractures
Yoshimi Tanaka, Koji Fukao, Yoshihisa Miyamoto +1
The relation between fracture surface morphology and the three-dimensional structure of crack fronts is investigated through direct observation of brittle cracks in gels. A key not…
