Visualizing Strain‐Coupled Cryogenic Phase Transitions and Defect Dynamics in Perovskite Quantum Dots Using In Situ STEM

Advanced Science
Perovskite quantum dots (PeQDs) offer high photoluminescence quantum efficiencies, precise spectral tunability, and solution‐processability, making them promising for advanced optoelectronics.

Effect of fibre orientation on the mechanical response of reinforced sand, detected with x-ray tomography [PDF]

E3S Web of Conferences
The mechanical behaviour of fibre-reinforced sands (FRS) has been thoroughly explored with a laboratory study, firstly investigating the influence of relevant parameters such as grading index, soil density, amount, diameter, and length of fibres then ...

Evaluation method with finite-element analysis for bending rupture limit of line pipe with high design factor

Nihon Kikai Gakkai ronbunshu, 2016
This study focused on ruptures due to bending deformation of steel pipe that is operated with a high design factor. The design factor refers to the ratio of the hoop stress from internal pressure to the yield strength of pipe material.

Strain Localization and Seismic Properties in the Heterogeneous Ailaoshan‐Red River Shear Zone, Southeast Asia

Geochemistry, Geophysics, Geosystems
Strain localization is crucial in developing crustal‐scale shear zones; however, a systematic analysis of deformation characteristics and their impact on seismic properties is still lacking.

Prediction of strain localization in nonlinear strain paths

, 2021
The simulation of nonlinear strain paths is important both for the design and development of tools for sheet metal forming processes, which can present very complex geometries, as well as for the prediction of failures during the process. Despite the evolution of computational methods, the prediction of ductile failure continues to be a challenge ...

Mathematical analysis of strain localization [PDF]

Revue Européenne de Génie Civil, 2007
ABSTRACT First it is shown by a simple one-dimensional example that stress-strain laws with softening cannot provide an objective description of response on the structural level. The phenomenon of discontinuous bifurcation from a uniform state is then analyzed in a general threedimensional setting.

Mapping the strain-localization evolution of grain boundary and its interactions with slip/twin at the microscale

Journal of Magnesium and Alloys
Plastic strain in polycrystalline metals is highly localized in grain boundaries (GBs), slip bands (SBs) and twins. While extensive research has focused on intra-granular deformation mechanisms such as slip and twinning, strain localization at GBs has ...
