Phase-field modeling of the interactions between an edge dislocation and an array of obstacles

S Xu, JY Cheng, Z Li, NA Mara, IJ Beyerlein - Computer Methods in Applied …, 2022 - Elsevier
Obstacles, such as voids and precipitates, are prevalent in crystalline materials. They
strengthen crystals by serving as barriers to dislocation glide. In this work, we develop a …

C Ji, Y Cui, Y Li, N Ghoniem - Journal of the Mechanics and Physics of …, 2022 - Elsevier
The vast majority of our current knowledge regarding the basic mechanisms controlling
irradiation effect on mechanical properties is based almost entirely on the results of post …

The statistic and fluctuant phenomena of interaction between edge extended dislocation and microvoid in FCC CoCrFeCuNi high entropy alloy

X Mei, Y Xu, Y Zhu, L Zhao, Z Li, M Huang - Journal of Nuclear Materials, 2022 - Elsevier
Irradiation induced microvoids in nuclear-service materials can act as obstacles for
dislocation glide and thus change the mechanical behavior of irradiated materials. High …

[HTML][HTML] Effects of elasticity and dislocation core structure on the interaction of dislocations with embedded CNTs in aluminium: An atomistic simulation study

S Nasiri, M Zaiser - Materialia, 2022 - Elsevier
The interaction between edge dislocations and carbon nanotubes (CNTs) embedded into an
Al matrix is investigated. Both pristine and Ni-coated CNTs are considered. It is …
