Modelling residual stresses in elastic bodies described by implicit constitutive relations
(Elsevier Ltd, 2018)
In this paper we study the response of bodies that are residually stressed within the context of a new class of constitutive relations, wherein the strains are assumed to be functions of the stresses. Such bodies are said ...
Residual stress mapping in TiN coatings by nanoindentation technique
(Volume 70, Issue 11, November 2012, Pages 1320-1325, 2012-11)
Abstract Titanium nitride (TIN) coatings were deposited on American Iron and Steel Institute (AISI) 410 stainless steel substrates by the cathodic arc physical vapor deposition process, varying the substrate bias voltage ...
Tensoes Residuais na Soldagem, Aspectos Basicos
The purpose of this paper is to analyze the basic aspects of the residual stresses in welding. Concepts about macro and micro residual stresses in metals are considered in welding. In a simple welding model is shown how ...
On the spectral analysis of residual stress in finite elasticity
(Oxford university press, 2017)
In the literature, residual stress problems are generally formulated using classical invariants despite most of them having an unclear physical meaning and not having experimental advantages. In this article, we give an ...
Effect of residual stresses and inclusion size on fatigue resistance of parabollic steel springs
(Carl Hanser Verlag, 2014-04-08)
The effect of inclusion size and residual stresses of spring steel grade 51CrV4 on fatigue lifetime in high cycle was investigated by experimental results obtained by fatigue testing. Since spring with obvious surface ...
Thermal cycles and residual stresses in FSW of aluminum alloys: experimental measurements and numerical models
In the present work longitudinal residual stresses obtained by different methods, numerical and experimental, in Friction StirWelding (FSW) process for AA7075 were analyzed. The experimental method employed for residual ...
Role of residual stress on phase transformations of Pb(Zr0.50Ti0.50)O3 thin films obtained from chemical route
abstract: The effects of heat treatment on the phase transformations of lead zirconate titanate Pb(Zr0.50Ti0.50)O3 (PZT) thin films were studied. The pyrolysis temperature directly affected the densification, residual ...
An evaluation of shot peening, residual stress and stress relaxation on the fatigue life of AISI 4340 steel
(Elsevier B.V., 2002-08-01)
Shot peening is a method widely used to improve the fatigue strength of materials. through the creation of a compressive residual stress field (CRSF) in their surface layers. In the present research the gain in fatigue ...
