Mechanisms during Strain Rate-Dependent Crack Propagation of Copper Nanowires Containing Edge Cracks

open access: yesNanomaterials, 2023
The crack propagation mechanism of Cu nanowires is investigated by using molecular dynamics methods. The microstructural evolution of crack propagation at different strain rates and crack depths is analyzed.

Propagation behavior of two collinear mode Ⅰ cracks driven by explosive gas

open access: yes矿业科学学报, 2023
In smooth pre-splitting blasting, two collinear cracks extending opposite to each other between adjacent holes will first avoid each other and then attract each other, resulting in crack propagation path that often presents hooked or butterfly-shaped ...

Crack Propagation in Quasicrystals [PDF]

open access: yesPhysical Review Letters, 1998
Crack propagation is studied in a two dimensional decagonal model quasicrystal. The simulations reveal the dominating role of highly coordinated atomic environments as structure intrinsic obstacles for both dislocation motion and crack propagation. For certain overloads, these obstacles and the quasiperiodic nature of the crystal result in a specific ...

Stress intensity factors and crack propagation path under mixed mode conditions [PDF]

open access: yesJournal of Structural and Construction Engineering, 2016
Use of crack propagation principles based on SIFs (stress intensity factors) is among the most common methods of fracture mechanic engineering. SIF is an important parameter in fracture analysis. In analyzing elastic fracture, SIF reveals the stress near
