Deformation vs. flow and wavelet-based models of gradient plasticity: Examples of axial symmetry
(2006)The modest goal of this article - the first in a series of three dedicated to Kirk Valanis - is to discuss and compare (in terms of their constitutive and variational formulation, boundary conditions and size-dependent ... -
Dependence of friction coefficient on the resolution and fractal dimension of metallic fracture surfaces
(2013)The paper studies the friction mechanism that is developed between metallic fracture interfaces of fractal geometry. The main purpose of the paper is to investigate how both the resolution and the fractal dimension of the ... -
Particle based simulation of fluid flow in periodically grooved channels
(2016)The method of Dissipative Particle Dynamics is applied to investigate the effect of the parameters employed to model the presence of periodic rectangular wall roughness on planar nanochannel flow. The parameters considered ... -
A second gradient elasto-plastic model for fatigue of small-scale metal components
(2010)Purpose - As the dimensions of structures are scaled down to the micro- and nano-domains, the mechanical behavior becomes size dependent and thus, the classical elasticity solutions cannot be expected to hold. In particular, ...
