Formulation method of ball indentation process for ultra-thin elastic body with mechanics poisson effect [PDF]
, 2019 A new theoretical method for determining the mechanics properties of ultra-thin elastic materials is proposed in this paper. This method is based on a full contact model and Poisson’s effect. This study consisted of three steps.

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Advanced Engineering Materials, EarlyView.This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Application of shell and solid elements in the analysis of building steel designs with software SCAD and Nastran accounting for geometrical and physical nonlinearity [PDF]
Инженерно-строительный журнал, 2011 Computational models using shell finite elements have a number of advantages in comparison with beam models, and their application can sometimes give essential improvements in design optimization, in the speed, presentation and simplicity of obtaining ...

To Solution of Contact Problem for Rectangular Plate on Elastic Half-Space
Наука и техника, 2020 Until the present time there is no exact solution to the contact problem for a rectangular plate on an elastic base with distribution properties. Practical analogues of this design are slab foundations widely used in construction.

On the Equivalence Problem for Toric Contact Structures on S^3-bundles over S^2$
, 2012 We study the contact equivalence problem for toric contact structures on $S^3$-bundles over $S^2$. That is, given two toric contact structures, one can ask the question: when are they equivalent as contact structures while inequivalent as toric contact ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
Advanced Engineering Materials, EarlyView.This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
