Development of a fretting-fatigue mapping concept: The effect of material properties and surface treatments [PDF]

, 2009
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components.

Microfluidic Adaptation of Density-Gradient Centrifugation for Isolation of Particles and Cells

Bioengineering, 2017
Density-gradient centrifugation is a label-free approach that has been extensively used for cell separations. Though elegant, this process is time-consuming (>30 min), subjects cells to high levels of stress (>350 g) and relies on user skill to ...

Classification of failure modes of pipelines containing longitudinal surface cracks using mechanics-based and machine learning models

Journal of Infrastructure Preservation and Resilience, 2023
This paper applies the mechanics-based approach and five machine learning algorithms to classify the failure mode (leak or rupture) of steel oil and gas pipelines containing longitudinally oriented surface cracks.

Channel Flow of a Tensorial Shear-Thinning Maxwell Model: Lattice Boltzmann Simulations

, 2013
We introduce a nonlinear generalized tensorial Maxwell-type constitutive equation to describe shear-thinning glass-forming fluids, motivated by a recent microscopic approach to the nonlinear rheology of colloidal suspensions.

The postulations á la D'Alembert and á la Cauchy for higher gradient continuum theories are equivalent. A review of existing results [PDF]

, 2015
In order to found continuum mechanics, two different postulations have been used. The first, introduced by Lagrange and Piola, starts by postulating how the work expended by internal interactions in a body depends on the virtual velocity field and its ...

Gradient Interfaces Induce the Temporal and Spatial Stress Localization in Gradient Network-Structured Metallic Glasses Composites

Metals
Gradient structure provides an effective approach to improve the combination of high strength and toughness compared to a uniform one. The gradient interfaces or boundaries in gradient-structured metallic glass composites play a crucial role in ...
