Effect of Initial Granular Structure on the Evolution of Contact Force Chains

Applied Sciences, 2019
The effect of initial granular structural conditions on load transmission patterns was experimentally investigated. Two types of granular structures were prepared by laminating cylindrical model particles of different diameters, to which photoelastic ...

Slit tube responses and rock fracture characteristics in slit charge blasting under high in situ stress

Deep Underground Science and Engineering, EarlyView.
In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

UNWRAPPING ISOCHROMATIC BY COMBINING WHITE LIGHT PHOTOELASTICITY WITH PHASE SHIFTING THCHNOLOGY

Jixie qiangdu, 2016
Use of a color code to identify fringe orders has been in use in conventional photoelasticity. Phase shifting technology is the most widely used for isochromatic evaluation due to its simplicity and accuracy. The phase shifting method obtain isochromatic

Spatially resolved stress measurements in materials with polarization-sensitive optical coherence tomography: image acquisition and processing aspects

, 2011
We demonstrate that polarization-sensitive optical coherence tomography (PS-OCT) is suitable to map the stress distribution within materials in a contactless and non-destructive way. In contrast to transmission photoelasticity measurements the samples do

Temperature‐robust exchange bias and spin‐orbit torque switching in van der Waals heterostructure

InfoMat, EarlyView.
Exchange bias (EB) in ferromagnetic/antiferromagnetic materials enables high‐density spintronic devices. A Fe3GaTe2/NiPS3 heterostructure exhibits EB up to 150 K, with spin orbit torque switching observed in both stacking orders. Interface layer effects induce net magnetism and magnetization flipping via Fe3GaTe2 domains, with strong interlayer ...

Exploiting Scattering‐Based Point Spread Functions for Snapshot 5D and Modality‐Switchable Lensless Imaging

Laser &Photonics Reviews, EarlyView.
This paper demonstrates a snapshot 5D and modality‐switchable lensless camera (Diffuser‐mCam), which can encode 2D intensity, multi‐spectral, polarization, and time information into a monochromatic raw data, and subsequently decode it using the compressed sensing algorithm at the sampling rate of 2.5% per channel.

A critical assessment of automatic photoelastic methods for the analysis of edge residual stresses in glass [PDF]

, 2014
The measurement of residual stresses is of great importance in the glass industry. The analysis of residual stresses in the glass is usually carried out by photoelastic methods since the glass is a photoelastic material.

Nondestructive Measurement of Residual Stress on Epoxy Insulators Using Thermoelastic Method

High Voltage, EarlyView.
ABSTRACT Residual stress is inevitable in epoxy insulators, which easily leads to small cracks and even insulation breakdown during the operation of gas‐insulated transmission line (GIL)/gas‐insulated switchgear (GIS). This study proposes a nondestructive method to measure the residual stress on epoxy insulators using thermoelastic effects.
