Rayleigh surface waves of extremal elastic materials [PDF]
J. Mech. Phys. Solids, 193(105842), 2024Extremal elastic materials here refer to a specific class of elastic materials whose elastic matrices exhibit one or more zero eigenvalues, resulting in soft deformation modes that, in principle, cost no energy. They can be approximated through artificially designed solid microstructures.

Non-modal elastic instability and elastic waves in weakly perturbed channel flow [PDF]
arXiv, 2021 In this paper, we present experimental results and reveal that strong perturbations are not necessary for elastic instability to occur in straight-channel, inertialess, visco-elastic flows at high elasticity. We show that a non-normal mode bifurcation is followed by chaotic fluctuations, self-organized as stream-wise streaks, and elastic waves due to ...

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer
Advanced Biology, EarlyView.Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

Advanced Engineering Materials, EarlyView.AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by

A midsurface elasticity model for a thin, nonlinear, gradient elastic plate [PDF]
arXiv, 2023 In this paper, we derive a dynamic surface elasticity model for the two-dimensional midsurface of a thin, three-dimensional, homogeneous, isotropic, nonlinear gradient elastic plate of thickness $h$. The resulting model is parameterized by five, conceivably measurable, physical properties of the plate, and the stored surface energy reduces to Koiter's ...

Numerical study on aerodynamic effects in passive pitching dynamics of insect flapping wings
Nihon Kikai Gakkai ronbunshu, 2014 This study is concerned with aerodynamic effects in passive pitching dynamics of insect flapping wings, which would be based on the Fluid-Structure Interaction (FSI). Thus, we evaluated them using three-dimensional numerical analyses for the FSI based on
