A Discrete Approach to Meshless Lagrangian Solid Modeling
Computation, 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 ...

Fixed 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]
MATEC 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.

Moving contact line problem: Advances and perspectives
Theoretical and Applied Mechanics Letters, 2014 The solid-liquid interface, which is ubiquitous in nature and our daily life, plays fundamental roles in a variety of physical-chemical-biological-mechanical phenomena, for example in lubrication, crystal growth, and many biological reactions that govern

Contact Mechanics for Solids with Randomly Rough Surfaces and Plasticity [PDF]
Lubricants, 2019 We present experimental results for the elastic and plastic deformation of sandblasted polymer balls resulting from contacts with flat smooth steel and silica glass surfaces. Nearly symmetric, Gaussian-like height probability distributions were observed experimentally before and remarkably, also after the polymer balls were deformed plastically.

Evaluation of the real contact area in three-body dry friction by micro-thermal analysis [PDF]
, 2009 Many tribological properties and wear mechanisms occurring on the micro-and nanoscale are strongly controlled by the so-called real contact area (Ar) which is a small fraction of the nominal or apparent contact area (Aa). The determination of Ar is often

Coupled irradiation-thermal-mechanical analysis of fuel in solid core of heat pipe cooled reactor
He jishuBackgroundHeat pipe cooled reactor (HPR) has many characteristics, such as reliability, inherent safety, small volume, modularity, and solid core. The nuclear fuel of solid core is seriously affected by high temperature, strong irradiation, and solid ...
