The structural instability of multi-walled carbon nanotubes(MWCNTs) has captured extensive attention due to the unique characteristic of extremely thin hollow cylinder structure. The previous studies usually focus on ...

We have proposed an"exact"strain gradient(SG)continuum model to properly predict the dispersive characteristics of diatomic lattice metamaterials with local and nonlocal interactions.The key enhancement is proposing a...

The dynamics of granular material discharging from a cuboid but thin hopper,including the hopper flow and granular jet,are investigated via discrete element method(DEM)simulations.The slot width is varied to study its...

Materials under complex loading develop large strains and often phase transformation via an elastic instability,as observed in both simple and complex systems.Here,we represent a material(exemplified for Si I)under la...

A diffusive-stochastic-viscoelastic model is proposed for the specific adhesion of viscoelastic solids via stochastically formed molecular bonds. In this model, we assumed that molecular level behaviours, including th...
This paper presents two specific thermodynamically consistent nonclassical continuum theories for solid and fluent continua.The first non-classical continuum theory for solid continua incorporates Jacobian of deformat...

A multi-scale model is developed to link the continuum damage variable in macroscale to the number density of multiple pits and cracks in microscale for studying the corrosion fatigue of aluminum alloy from multi-scal...
The paper addresses the formulation of rate equations, via objective time derivatives, within continuum physics. The concept of objectivity is reviewed and distinction is made with material frame-indifference whose me...

Plastic deformation of small crystals occurs by power-law distributed strain avalanches whose universality is still debated. In this work we introduce a continuum crystal plasticity model for the deformation of micros...
The article examines the cognitive and pragmatic potential of proper names within literary discourse. Since the question of the semantics of proper names is rather acute within the modem linguistic studies, the resear...
