Pre‐Torsion Tubular Metamaterials: Multi‐Effect Integration for Advanced Functional Applications [PDF]

open access: yesAdvanced Science
Mechanical metamaterials continuously push the boundaries of mechanical properties far beyond conventional materials. However, a critical step toward the applications of metamaterials lies in combining multiple effects and functionalities into a single ...

Influence of Topological Defects on the Mechanical Response of Unit Cells of the Tetrachiral Mechanical Metamaterial

open access: yesDesigns, 2023
The primary benefit of metamaterials is that their physical and mechanical properties can be controlled by changing the structure geometry. Numerical analysis tools used in this work offer a few advantages over full-scale testing, consisting of an ...

Stress-strain and microscopy data for fire-damaged aluminum alloy 6061 subjected to multiaxial loading

open access: yesData in Brief, 2021
Stress/strain data from mechanical testing of samples obtained from “as received” and fire damaged (400 °C and 500 °C) aluminum alloy 6061 plates is reported. Mechanical load information was obtained from load cells in the mechanical testing system while

Mechanics of ventricular torsion

open access: yesJournal of Biomechanics, 1996
Recent research suggests that left ventricular torsion is an important indicator of cardiac function. We used two theoretical models to study the mechanics of this phenomenon: a compressible cylinder and an incompressible ellipsoid of revolution. The analyses of both models account for large- strain passive and active material behavior, with a muscle ...

Kalker’s coefficient c11 and its influence on the damping and the retuning of a mechanical drive torsion system of a railway vehicle

open access: yesActa Polytechnica CTU Proceedings, 2022
Within the research of electromagnetically excited torsion oscillations in the mechanical part of traction drive systems of modern railway vehicles, which has been realized at the Faculty of mechanical engineering at the CTU in Prague, there are two ...

Design, dynamics, and dissipation of a torsional-magnetic spring mechanism

open access: yesMechanical Systems and Signal Processing, 2022
We present an analytical and experimental study of torsional magnetic mechanism where the restoring torque is due to magnetic field interactions between rotating and fixed permanent magnets. The oscillator consists of a ball bearing-supported permanent magnet, called the rotor, placed between two fixed permanent magnets called the stators.

“Quasi-complete” mechanical model for a double torsion pendulum [PDF]

open access: yesPhysical Review D, 2013
We present a dynamical model for the double torsion pendulum nicknamed PETER, where one torsion pendulum hangs in cascade, but off-axis, from the other. The dynamics of interest in these devices lies around the torsional resonance, that is at very low frequencies (mHz).

Fiber-Optic Sensors for Measurements of Torsion, Twist and Rotation: A Review

open access: yesSensors, 2017
Optical measurement of mechanical parameters is gaining significant commercial interest in different industry sectors. Torsion, twist and rotation are among the very frequently measured mechanical parameters. Recently, twist/torsion/rotation sensors have

Quantification of Friction Force on Dual-Axis Micro-Mechanical Probe for Friction Force Microscopy

open access: yesTribology Online, 2010
Conventional friction force microscopes (FFMs), where micro cantilever probes are used, have a disadvantage that the accurate quantification of friction force has not been established yet.
