Initiation and stagnation of room temperature grain coarsening in cyclically strained gold films [PDF]
Acta Materialia, 2019 Despite the large number of experiments demonstrating that grains in a metallic material can grow at room temperature due to applied mechanical load, the mechanisms and the driving forces responsible for mechanically induced grain coarsening are still ...

Effect of local anisotropy on fatigue crack initiation in a coarse grained nickel-base superalloy
MATEC Web of Conferences, 2018 In the present work, theoretical approaches, based on grain orientation dependent Young’s modulus and Schmid factor are used to describe the influence of local grain orientation on crack initiation behaviour of the coarse grained nickel base superalloy ...

Roles of phytohormone changes in the grain yield of rice plants exposed to heat: a review [PDF]
PeerJ, 2019 During its reproductive phase, rice is susceptible to heat stress. Heat events will occur at all stages during the reproductive phase of rice as a result of global warming.

Analysis of Grain’s Initialization Algorithm [PDF]
, 2008 In this paper, we analyze the initialization algorithm of Grain, one of the eSTREAM candidates which made it to the third phase of the project. We point out the existence of a sliding property in the initialization algorithm of the Grain family, and show that it can be used to reduce by half the cost of exhaustive key search (currently the most ...

Forecast of the fatigue crack initiation site of commercially pure Titanium miniature specimens with local surface topography data [PDF]
MATEC Web of Conferences, 2020 Surfaces of technical components rarely appear in perfectly smooth condition. During fatigue loading, stress concentrations at surface asperities cause localized plastic deformation that can lead to crack initiation.

A three-dimensional multiscale model of intergranular hydrogen-assisted cracking [PDF]
, 2010 We present a three-dimensional model of intergranular hydrogen-embrittlement (HE) that accounts for: (i) the degradation of grain-boundary strength that arises from hydrogen coverage; (ii) grain-boundary diffusion of hydrogen; and (iii) a continuum model

The initial structure of chondrule dust rims II: Charged grains [PDF]
Icarus, 2021 In order to characterize the early growth of fine-grained dust rims (FGRs) that commonly surround chondrules, we simulate the growth of FGRs through direct accretion of monomers of various sizes onto the chondrule surfaces. Dust becomes charged to varying degrees in the radiative plasma environment of the solar nebula (SN), and the resulting ...

A fatigue crack initiation model incorporating discrete dislocation plasticity and surface roughness [PDF]
, 2007 Although a thorough understanding of fatigue crack initiation is lacking, experiments have shown that the evolution of distinct dislocation distributions and surface roughness are key ingredients.
