Direct evidence of plastic events and dynamic heterogeneities in soft-glasses [PDF]

open access: yes, 2014
By using fluid-kinetic simulations of confined and concentrated emulsion droplets, we investigate the nature of space non-homogeneity in soft-glassy dynamics and provide quantitative measurements of the statistical features of plastic events in the ...

Design and experimental research of pipeline stress measurement system based on alternating current field

open access: yesYou-qi chuyun, 2023
Ferromagnetic pipelines are prone to stress distortion during service, which will likely cause destructive defects, such as fatigue damage and cracks, and even major safety accidents in severe cases.

Preparation of Samples used in Fatigue Testing of Aircraft Materials

open access: yesFatigue of Aircraft Structures, 2015
The application of a new type of alloy requires the evaluation of its properties, which is typically achieved with destructive methods. For this purpose, among others, static and fatigue mechanical tests are performed. Tests are performed on standardized

Development and Validation of a Novel Method Using QuEChERS and UHPLC-MS-MS for the Determination of Multiple Emerging Fungicides in Surface Waters

open access: yesSeparations
The increasing global reliance on pesticides for agricultural pest control has raised significant environmental concerns, particularly due to inadequate monitoring of emerging chemicals in surface waters.

The Refraction Indices and Brewster Law in Stressed Isotropic Materials and Cubic Crystals

open access: yesCrystals, 2021
We study the elasto-optic behavior of stressed cubic crystals (all classes) and isotropic materials (like e.g., glasses). We obtain the explicit dependence of the refraction indices on the stress (either applied or residual), as well as a mild ...

Stress dependent thermal pressurization of a fluid-saturated rock [PDF]

open access: yes, 2009
Temperature increase in saturated porous materials under undrained conditions leads to thermal pressurization of the pore fluid due to the discrepancy between the thermal expansion coefficients of the pore fluid and of the solid matrix.

Robustness of the Data-Driven Identification algorithm with incomplete input data [PDF]

open access: yesJournal of Theoretical, Computational and Applied Mechanics
Identifying the mechanical response of a material without presupposing any constitutive equation is possible thanks to the Data-Driven Identification algorithm developed by the authors.
