Dislocations are commonly present and important in metals but their effects have not been
fully recognized in oxide ceramics. The large strain energy raised by the rigid ionic/covalent …

A traction–displacement relationship that may be embedded into a cohesive zone model for
microscale problems of intergranular fracture is extracted from atomistic molecular-dynamics …

Crack-tip behaviour in metals is among the most basic problems in mechanics of materials.
Yet, long-standing experimental evidence suggests that crack-tip twinning in face-centred …

The nano-mechanics method has recently emerged as a powerful computational approach
to model from nano to macro microstructure deformation and failure behaviours in materials …

In this paper, we present a peridynamic (PD)-based solution for discrete dislocation
dynamics (DDD) problems using the superposition (SP) framework. By replacing the …

Twinning in metals is normally a permanent plastic deformation mechanism. Here we report
reversible twinning in high stacking fault energy (SFE) aluminum. Twinning and …

We present a thermodynamic description of decohesion that provides a link between first
principles studies of decohesion and cohesive zone models used in continuum simulations …

Recent experimental evidence has shown that even fcc materials that are not normally
associated with deformation twinning, such as aluminum, will twin given a sufficiently high …

Molecular statics is used to study the crack propagation in model nanocrystalline Ni with a
mean grain size of 10nm. It is shown that the crack propagates intergranularly, creating nano …

Hydrogen ingression in metals generally causes catastrophic failure. The H-induced fracture
surface mostly exhibits intergranular feature, suggesting that grain boundary (GB) is the …
