Apparent Breakdown of the Stress-Optic Rule in Rigid-Rod Suspensions: A Stress-Partitioning Interpretation
William Kai Alexander Worby, Yuto Yokoyama, Misa Kawaguchi +1
A fundamental problem in the field of anisotropic macromolecular materials concerns how the flow-induced orientational order connects microscopic structure to macroscopic rheologic…
Interfacial dynamics induced by impacts across rigid and soft substrates
Ishin Kikuchi, Hiroya Watanabe, Yuto Yokoyama +2
We investigate impact-induced gas-liquid interfacial dynamics through experiments in which a liquid-filled container impacts substrates with elastic moduli from MPa to…
Droplet impact on elastic substrates: force scaling crossover
Yuto Yokoyama, Hirokazu Maruoka, Yoshiyuki Tagawa
Droplet impacts are fundamental to fluid-structure interactions, shaping processes from erosion to bioprinting. While previous scaling laws have provided insights into droplet dyna…
Examination of flow birefringence induced by the shear components along the optical axis using a parallel-plate-type rheometer
William Kai Alexander Worby, Kento Nakamine, Yuto Yokoyama +2
In this study, the concept of rheo-optics is applied that explores the flow birefringence caused by stress components along the optical axis of the camera since it is often overloo…
High-speed photoelastic tomography for axisymmetric stress fields in a soft material: temporal evolution of all stress components
Yuto Yokoyama, Sayaka Ichihara, Yoshiyuki Tagawa
This study presents a novel approach for reconstructing all stress components of the dynamic axisymmetric fields of a soft material using photoelastic tomography (PT) and a high-sp…
