The Optimal Transportation Method in Solid Mechanics [PDF]

open access: yes, 2009
This dissertation is concerned with the development of a robust and efficient meshless method, the Optimal Transportation Method (OTM), for general solid flows involving extremely large deformation, fast, transient loading and hydrodynamic phenomena ...

Application of the continuum shell finite element SHB8PS to sheet forming simulation using an extended large strain anisotropic elastic–plastic formulation [PDF]

open access: yes, 2012
http://link.springer.com/article/10.1007%2Fs00419-012-0620-xThis paper proposes an extension of the SHB8PS solid–shell finite element to large strain anisotropic elasto-plasticity, with application to several non-linear benchmark tests including sheet ...

From the Fan-KKM principle to extended real-valued equilibria and to variational-hemivariational inequalities with application to nonmonotone contact problems

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2022
This paper starts off by the celebrated Knaster–Kuratowski–Mazurkiewicz principle in the formulation by Ky Fan. We provide a novel variant of this principle and build an existence theory for extended real-valued equilibrium problems with general, then ...

Computational and experimental diagnostics of the shear properties of greases [PDF]

open access: yesMATEC Web of Conferences, 2021
The study of the properties of consistent and liquid oils is currently receiving much attention in tribology. This is because lubrication is one of the most effective ways to improve machine durability.

Collisions in a liquid fluidized bed [PDF]

open access: yes, 2011
Collisional phenomena in a solid–liquid flow were studied in terms of two parameters: the collision frequency and the coefficient of restitution. Experimental measurements of these parameters were conducted inside a liquid fluidized bed by particle ...

The Influence of Wheel/Rail Contact Conditions on the Microstructure and Hardness of Railway Wheels [PDF]

open access: yes, 2014
The susceptibility of railway wheels to wear and rolling contact fatigue damage is influenced by the properties of the wheel material (microstructure and hardness).

A Discrete Approach to Meshless Lagrangian Solid Modeling

open access: yesComputation, 2017
The author demonstrates a stable Lagrangian solid modeling method, tracking the interactions of solid mass particles rather than using a meshed grid. This numerical method avoids the problem of tensile instability often seen with smooth particle applied ...

A review of some tribo-dynamics phenomena from micro- to nano-scale conjunctions [PDF]

open access: yes, 2009
The paper provides some highlights in the developments of theories of lubrication and contact mechanics from early pioneering works of Reynolds and Hertz to the establishment of elastohydrodynamic phenomenon by Ertel and Grubin. Some historical discourse

Finite element based surface roughness study for ohmic contact of microswitches [PDF]

open access: yes, 2012
Finite element method (FEM) is used to model ohmic contact in microswitches. A determinist approach is adopted, including atomic force microscope (AFM) scanning real contact surfaces and generating rough surfaces with three-dimensional mesh.

A meshfree computational framework for the numerical simulation of the solid-state additive manufacturing process, additive friction stir-deposition (AFS-D)

open access: yesMaterials & Design, 2021
In this work, a fully coupled thermo-mechanical meshfree approach is developed for the first time to simulate a solid-state layer-by-layer additive manufacturing process, Additive Friction Stir-Deposition (AFS-D). The meshfree method in this present work
