Effects of boundary condition and cell structure on dynamic axial crushing honeycomb

Mechanical Engineering Journal, 2018
The dynamic axially crushing behavior of metal honeycombs was studied with placing emphasis on the effects of boundary condition and cell structure on its characteristics as an energy absorber. Numerical honeycomb models of some metal foil materials were

Frequency Domain Simulations of Charge-Density-Wave Strains: Comparison with Electro-Optic Measurements

, 2007
We have studied changes in charge-density-wave strain under application of square-wave currents of variable amplitude and frequency by numerically solving the phase-slip augmented diffusion model introduced by Adelman et al (Phys. Rev. B 53, 1833 (1996)).

Quenched disorder induced magnetization jumps in (Sm,Sr)MnO$_3$ [PDF]

, 2004
Magnetic field induced step-like changes in magnetization and resistivity of SmSr manganites were studied. A strong dependence of these features on the cooling rate was observed.

Effect of high strain rate on micro-indentation test in pure aluminum

EPJ Web of Conferences, 2012
The indentation properties of pure aluminum (99.9%, 3N aluminum) and high purity aluminum (99.999%, 5N aluminum) with respect to the strain rate dependence of strength are experimentally investigated in order to clarify the effect of strain rate on the ...

One-dimensional modeling of necking in rate-dependent materials [PDF]

, 2019
This paper presents an asymptotically rigorous one-dimensional analytical formulation capable of accurately capturing the stress and strain distributions that develop within the evolving neck of bars and sheets of rate-dependent materials stretched in ...

Strain rate dependent mechanical properties in single crystal nickel nanowires [PDF]

, 2013
We measure the strain rate dependence of 0.2% offset yield stress in single-crystal nickel nanowires with diameters ranging from 80 to 300 nm. In situ tensile experiments with strain rates from 10 4 s 1 to 10 2 s 1 were conducted, and the small ...

Study of Uniaxial Tensile Properties of Hexagonal Boron Nitride Nanoribbons

, 2017
Uniaxial tensile properties of hexagonal boron nitride nanoribbons and dependence of these properties on temperature, strain rate, and the inclusion of vacancy defects have been explored with molecular dynamics simulations using Tersoff potential.

Recent Milestones in Unraveling the Full-Field Structure of Dynamic Shear Cracks and Fault Ruptures in Real-Time: From Photoelasticity to Ultrahigh-Speed Digital Image Correlation [PDF]

, 2020
The last few decades have seen great achievements in dynamic fracture mechanics. Yet, it was not possible to experimentally quantify the full-field behavior of dynamic fractures, until very recently.
