Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

A New Large Impact Torsion Testing Machine

Journal of the Society of Materials Science, Japan, 1966
The large impact torsion testing machine which has recently been designed and constructed by the present authors, has the capacity of 100kg-m and the rotating speed from 100rpm to 2600rpm. This machine is fit to make intermittent loading, the detection of axial stress caused during the torsional deformation and the tests under combined stress by adding

On the Impact Torsional Test by Means of a Dropped Bar

Transactions of the Japan Society of Mechanical Engineers, 1978
In the present paper we describe the impact torsional stress of a circular bar supported horizontally and subjected to impact torsion, when a cross pin attached to the end of it was struck by a dropped bar. Stresses obtained by experiments were in good agreement with those by one dimensional theory except for the short time after the impact.

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...
