Time-Resolved Stress Analysis of Tissue Simulants During Needle-Free Jet Injection
Kohei Yamagata, Prasad Sonar, Kazuhiro Terai +2
Needle-free jet injection generates transient internal stress fields that can influence tissue deformation, pain-related stimulation, and cellular-level mechanical responses. Howev…
Full-component reconstruction of three-dimensional fluid stress tensors
Shunsuke Kumagai, Shun Miyatake, Ryusuke Cho +5
Forces govern how fluids deform biological tissues, regulate cardiovascular function, and determine the performance and failure of soft materials. Recent advances in flow birefring…
Penetration of impact-induced jets into skin-simulating materials
Kohei Yamagata, Yuto Yokoyama, Shoto Sekiguchi +3
This study compares the penetration characteristics of impact-induced jets with those of laser-induced jets, focusing on the underlying penetration mechanism rather than device per…
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…
Extending flow birefringence analysis to combined extensional-shear flows via Jeffery-Hamel flow measurements
Miu Kobayashi, William Kai Alexander Worby, Misa Kawaguchi +3
This study investigates the relationship between phase retardation and strain rates in combined extensional-shear flows using the Jeffery-Hamel flow formalism, which yields an anal…
Reconstruction of three-dimensional fluid stress field via photoelasticity using physics-informed convolutional encoder-decoder
Daichi Igarashi, Shunsuke Kumagai, Yuto Yokoyama +3
Measuring stress fields in fluids and soft materials is crucial in various fields such as mechanical engineering, medicine, and bioengineering. However, conventional methods that c…
