The Buckling of Single-Layer MoS2 Under Uniaxial Compression

open access: yes, 2014
Molecular dynamics simulations are performed to investigate the buckling of single-layer MoS2 under uniaxial compression. The strain rate is found to play an important role on the critical buckling strain, where higher strain rate leads to larger ...

Study of Uniaxial Tensile Properties of Hexagonal Boron Nitride Nanoribbons

open access: yes, 2017
Uniaxial tensile properties of hexagonal boron nitride nanoribbons and dependence of these properties on temperature, strain rate, and the inclusion of vacancy defects have been explored with molecular dynamics simulations using Tersoff potential.

Strain Rate Dependence of PLC Effect in AlMg4.5 Alloys

open access: yesEngineering Proceedings
Tensile tests of AlMg4.5 alloy were carried out at six strain rates to study the Portevin–Le Chatelier (PLC) effect. The measured engineering stress–time and engineering stress–engineering strain curves were evaluated by direct peak detection and ...

Strain rate sensitivity of mechanical properties of the ZK60 alloy with the high degree of corrosion damage

open access: yesFrontier Materials & Technologies, 2023
There is a strong belief that hydrogen absorbed by magnesium alloys during corrosion can cause their stress corrosion cracking. One of the characteristic markers indicating the involvement of diffusible hydrogen into the fracture mechanism of metals is ...
