First approach to unilateral transfemoral amputees' contact mechanics

open access: yesDyna, 2017
The stresses in the hip area have great importance because of their relationship to the health of the joint. Finite element models can predict contact between cartilages, however, contact patterns in unilateral transfemoral amputees have not yet been ...

A note on the effect of surface topography on adhesion of hard elastic rough bodies with low surface energy

open access: yesJournal of the Mechanical Behavior of Materials, 2019
Adhesion between bodies is strongly influenced by surface roughness. In this note, we try to clarify how the statistical properties of the contacting surfaces affect the adhesion under the assumption of long-range adhesive interactions.

Tykhonov well-posedness of fixed point problems in contact mechanics

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2022
We consider a fixed point problem S u = u $\mathcal {S}u=u$ where S : C ( R + ; X ) → C ( R + ; X ) ${\mathcal {S}:C(\mathbb{R}_{+};X)\to C(\mathbb{R}_{+};X)}$ is an almost history-dependent operator.

Biomechanical Evaluation of Isotropic and Shell-Core Composite Meniscal Implants for Total Meniscus Replacement: A Nonlinear Finite Element Study

open access: yesIEEE Access, 2019
Loss of meniscal function due to symptomatic meniscal tears or meniscectomy leads to biomechanical instability and articular cartilage degeneration. Synthetic meniscal implants ought to ideally restore normal joint contact mechanics and thus forfending ...

Contact mechanics and friction: Role of adhesion

open access: yesFriction
This paper presents an overview of the role of adhesion in various tribological phenomena. We discuss (1) adhesion and adhesive hysteresis in rough contacts, (2) adhesive contribution to dry friction, (3) properties of adhesive contacts under tangential ...

Experimental study of sand grains behavior at their contacts with force- and displacement-controlled sliding tests

open access: yesUnderground Space, 2017
Discrete element modeling requires the proper quantification of the behavior of grains at their contacts including the normal force – displacement and tangential force – displacement relationships to be used as input for contact modeling purposes.

Elastic and Elastoplastic Contact Mechanics of Concentrated Coated Contacts

open access: yesLubricants
Machines operate under increasingly harsher contact conditions, causing significant wear and contact fatigue. Sub-surface stresses are responsible for the premature contact fatigue of rolling element bearings, meshing gears, and cam–follower pairs ...
