Tensoes Residuais na Soldagem, Aspectos Basicos
(1995-12-01)
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 ...
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 ...
Role of residual stress on phase transformations of Pb(Zr0.50Ti0.50)O3 thin films obtained from chemical route
(2016-07-14)
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 ...
Residual stresses explaining clinical fractures of bilayer zirconia and lithium disilicate crowns: A VFEM study
(2021-01-01)
Objective: To understand the stress development in porcelain-veneered zirconia (PVZ) and porcelain-veneered lithium disilicate (PVLD) crowns with different veneer/core thickness ratios and cooling rates. To provide design ...
Evaluation of stresses generated by welding in API 5L X65 steel using acoustoelasticity

Study of Residual Stresses from Two Machining Protocols Using an Indentation Method
(Science Publishing, 2013-09)
Although high-speed machining offers a number of advantages over conventional machining, it is possible that the residual stress distributions generated by the former can affect the service life of the processed components. ...
Microstructural and Residuals Stress Analysis of Friction Stir Welding of X80 Pipeline Steel Plates Using Magnetic Barkhausen Noise
(2019-12-01)
Friction stir welding is a solid-state joining method conducted under large stress and strain conditions at low peak temperatures when compared to arc welding. Friction stir welding produces a large variety of microstructures ...
