An automatic identification method for width of shear band of sand in PFC simulations

Yantu gongcheng xuebao, 2022
Studying the strain localization of granular materials from the meso-scale is helpful for deeply understanding the physical and mechanical natures of strain localization, and the occurrence and evolution of shear bands are the typical characteristics of ...

Microstructure dependent strain localization during primary hot working of TA15 titanium alloy: Behavior and mechanism

Materials & Design, 2021
Strain localization, a cross-scale issue degrading homogeneity and formability during hot working of TA15 titanium alloy, is complicated by lamellar microstructure for hierarchical feature, spatial morphology, and orientation relationship.

Investigation on strain localization and hardening of dual-phase steel by hetero-deformation induced stress

Journal of Materials Research and Technology, 2023
Strain hardening remains challenging for maintaining the plasticity of metals, especially those of high strength. The hetero-deformation induced (HDI) stress can effectively alleviate the problem, specifically with a large mechanical response mismatch ...

The value of local malaria strains for serological studies: local strains versus Palo Alto reference strain [PDF]

Malaria Journal, 2015
The standardization of the type of crude Plasmodium falciparum extracts for assays to evaluate the overall anti-blood-stage immune response in humans may be beneficial to malaria pre-elimination programmes. However, there is no consensus on which strain is appropriate for routine analyses.

Impurity Analysis and Microstructure Along the Climatic Transition From MIS 6 Into 5e in the EDML Ice Core Using Cryo-Raman Microscopy

Frontiers in Earth Science, 2019
Impurities in polar ice cores have been studied so far mainly for the purpose of reconstructions of past atmospheric aerosol concentrations. However, impurities also critically influence physical properties of the ice matrix itself.

Evolution of Shear Band in Plane Strain Compression of Naturally Structured Clay with a High Sensitivity

Applied Sciences, 2022
The formation of the shear band is associated with the failure of soil. However, there has been relatively little investigation on the evolution of shear bands in naturally structured clay with a high sensitivity.
