Experimental investigation of friction in compliant contact: The effect of configuration, viscoelasticity and operating conditions
(2022)
This work investigates the effects of kinematic conditions, configuration, viscoelasticity, and lubricant viscosity on friction in lubricated compliant contacts. Experimental data were also used to develop a numerical ...
Immunopathology of allergic contact dermatitis
(SOC BRASILEIRA DERMATOLOGIA, 2011)
Allergic contact dermatitis is the consequence of an immune reaction mediated by T cells against low molecular weight chemicals known as haptens. It is a common condition that occurs in all races and age groups and affects ...
Unilateral contact condition enhanced with squeeze film modelling in automotive differentials
(Professional Engineering Publishing Ltd, 2016-03)
The dynamic behaviour of automotive drivetrains is significantly influenced by contacts occurring between the various parts. In this paper, a three-dimensional formulation is proposed to model unilateral and frictional ...
Behavior of adhesion forces of the aqueous-based polychloroprene adhesive magnetically conditioned
(Zeis, 2016-03)
This research is an innovation proposal for magnetic conditioning of the aqueous-based polychloroprene contact adhesive with the purpose of increasing the adherence capacity between the adhesive and the substrate. Today, ...
C^l-contact and C^l-right equivalences of real semi-quasihomogeneous C^l-function germs
(2014)
In this paper we investigate the C ` versions of contact and right equivalences of real semi-quasihomogeneous C ` function germs, 1 ≤ ` ≤ ∞. The C ` -right equivalence implies C ` -contact equivalence for any 1 ≤ ` ≤ ∞ and ...
Finite strain model for contact interface in forming processes
(Wiley, 2006-12)
A phenomenological rate and state-variable friction law for the continuous sliding under lubricated and dry conditions, asit occurs in metal forming processes, is presented in this paper. The contact model is developed ...
Computational modeling of 2D frictional contact problems based on the use of coupling finite elements and combined contact/friction damage constitutive model
(2022-02-01)
This work proposes a new approach to describe 2D frictional contact problems based on the use of coupling finite elements (CFEs) and a combined contact/friction damage constitutive model. This technique is able to establish ...
Rolling contact fatigue resistance of Carbidic Austempered Ductile Iron (CADI)
(Elsevier Science SA, 2019-01)
The austempered ductile iron (ADI) with carbides in its microstructure, commonly known as CADI, is a relatively new variant of ductile iron intended to resist abrasive wear in different tribosystems by selecting the ...
Cl-contact and Cl-right equivalences of real semi-quasihomogeneous Cl function germs
(2014-01-01)
In this paper we investigate the Cl versions of contact and right equivalences of real semi-quasihomogeneous Cl function germs, 1 ≤ l ≤ ∞. The Cl-right equivalence implies Cl-contact equivalence for any 1≤ l ≤ ∞ and in ...
Evaluation of Different Conditions of Contact for Caprolactam Migration from Multilayer Polyamide Films into Food Simulants
(Wiley-Blackwell, 2014-06-01)
Caprolactam, the polyamide 6 (PA-6) monomer, can migrate during food processing. At cooking temperatures, migration is accelerated and plastic components could degrade, giving off low molecular mass compounds, which can ...
