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…
