Mathematics in Finite Element Modeling of Computational Friction Contact Mechanics 2021–2022
Mathematics, 2023 In engineering practice, structures with identical components or parts are useful from several points of view: less information is needed to describe the system; designs can be conceptualized quicker and easier; components are made faster than during ...

Classical and numerical approaches to determining V-section band clamp axial stiffness [PDF]
Open Engineering, 2014 V-band clamp joints are used in a wide range of applications to connect circular flanges, for ducts, pipes and the turbocharger housing. Previous studies and research on V-bands are either purely empirical or analytical with limited applicability on the ...

How friction and adhesion affect the mechanics of deep penetration in soft solids
Soft Matter, 2022 Friction and adhesion create an increment in penetration force with the depth of the penetrator (needle) tip. This work provides the correlation between the force increment, the material properties and the needle radius.

Implementation of Dahl’s dynamic friction model to contact mechanics of elastic solids [PDF]
SN Applied Sciences, 2021 AbstractThis study presents an analytical method for the solution of dynamic frictional contact problem between a rigid punch and an isotropic elastic solid. Rigid flat punch moves over the isotropic elastic solid at a constant subsonic speed and friction force develops based on Dahl’s friction law instead of Coulomb’s dry friction law.

Exploring the influence of friction in the puncture mechanics of soft solids
MeccanicaAbstract Friction is an ever-present force in our lives, affecting the interaction between objects in numerous ways. The common hypothesis of frictionless contact between a foreign rigid object (needle) and a target material during puncturing leads to a constant penetration force.

Quantum-Scale Friction at Solid-Liquid Interface: Simulation, Detection Techniques, Mechanisms, and Emerging Applications. [PDF]
Nanomicro LettAbstract Solid–liquid interfaces are ubiquitous in nature and engineering, and their frictional behavior remains a key factor limiting performance gains in surface engineering. However, conventional tribology has largely focused on the effect of macroscopic variables such as surface topography, which do not account for the microscopic
