Hydrogen embrittlement is a complex phenomenon, involving several length-and
timescales, that affects a large class of metals. It can significantly reduce the ductility and …

Any fracture process ultimately involves the rupture of atomic bonds. Processes at the atomic
scale therefore critically influence the toughness and overall fracture behavior of materials …

Nanoscale features present in structural and functional materials affect their macroscopic
properties and hence have been extensively studied. As experimental investigations of …

The inter-hole interference of nickel-based single crystal film-cooling holes specimen during
creep deformation were investigated by both experiment and crystal plastic finite element …

The interaction between dislocations and precipitates plays an essential role in
strengthening mechanisms of the Ni-based superalloys (γ-Ni, γ′-Ni 3 Al). It is worth noting …

Fracture properties of a material are strongly influenced by the presence of defects. In view
of this, molecular dynamics simulations were performed within the framework of embedded …

In recent years, tubing failure often occurs in the ultra-deep oil and gas well with the complex
geological condition, resulting in accidents and repairs during the service process in the …

Molecular dynamics simulations were conducted to elucidate dislocation mechanisms of the
void growth and coalescence in single crystal and nanotwinned nickels subjected to uniaxial …

Silicene has become a topic of interest nowadays due to its potential application in various
electro-mechanical nanodevices. In our previous work on silicene, fracture stresses of single …

Linear elastic fracture mechanics establishes the conditions necessary for crack arrest by
the introduction of a hole in its path. However, it is unclear how nanoscale crack-vacancy …
