Mechanical properties of Graphene Nanoribbons

, 2009
Herein, we investigate the structural, electronic and mechanical properties of zigzag graphene nanoribbons upon the presence of stress applying Density Functional Theory within the GGA-PBE approximation.

Effects of the grain size and shape on the flow stress: A dislocation dynamics study [PDF]

, 2019
Dislocation dynamics simulation is used to investigate the effect of grain size and grain shape on the flow stress in model copper grains. We consider grains of 1.25-10 $\mu$m size, three orientations (, and ) and three shapes (cube, plate and needles).

Avalanches, loading and finite size effects in 2D amorphous plasticity: results from a finite element model [PDF]

, 2015
Crystalline plasticity is strongly interlinked with dislocation mechanics and nowadays is relatively well understood. Concepts and physical models of plastic deformation in amorphous materials on the other hand - where the concept of linear lattice ...

Micromechanical response of fibre-reinforced materials using the boundary element technique [PDF]

, 2003
The Boundary Element Method (BEM) and the Embedded Cell Approach (ECA) have been used to analyse the effects of constituent material properties and fibre spatial distribution on the localised behaviour of a transversely loaded, unidirectional fibre ...

Effect of Curing Stress and Period on the Mechanical Properties of Cement-Mixed Sand

Soils and Foundations, 2011
ABSTRACT Cement mixing is one of the popular ground improvement technologies in geotechnical engineering practice. In order to effectively and confidently design cement-mixed soil structures for specific purposes, its stress-strain behavior needs to be well understood. Though there have been many studies on cement-mixed soils using different types of

Experimental and simulation investigation on thermal-vibratory stress relief process for 7075 aluminium alloy

Materials & Design, 2020
Residual stresses evidently affect the strength, fatigue property and machining deformation of the mechanical components. Therefore, stress relief processes are extensively applied in the manufacturing to enhance the mechanical properties of products. In
