3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response
Advanced Engineering Materials, EarlyView.A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

Study on optimal design of mistuned bladed disk
Nihon Kikai Gakkai ronbunshu, 2018 Although, in designing blades, it is assumed that all blades on a disk are identical (tuned system), the vibration characteristics of the blade is slightly different due to the manufacturing tolerance, the deviation of the material property, and so on ...

Steady-state forced vibrations [PDF]
International Journal of Non-Linear Mechanics, 1966 The following concepts are defined: (i) periodic functions possessing an amplitude, (ii) cosine-like functions, (iii) steady-state forced vibrations. The following theorems are proved: I. If, in $\ddot{x} + f(x) = P g(t) P g(t + T)$, $x(0) = X \neq 0$, $0 < P < \infty$, $-\infty < t < + \infty$, $g(t)$ is cosine-like, a necessary condition for the ...

Advanced Functional Materials, EarlyView.In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Vibration as an exercise modality: how it may work, and what its potential might be [PDF]
, 2010 Whilst exposure to vibration is traditionally regarded as perilous, recent research has focussed on potential benefits. Here, the physical principles of forced oscillations are discussed in relation to vibration as an exercise modality.

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.
