Analysis of Residual Stresses in Laser-Shock-Peened and Shot-Peened Marine Steel Welds [PDF]

, 2016
Laser peening is now the preferred method of surface treatment in many applications. The magnitude and depth of the compressive residual stress induced by laser peening can be influenced strongly by the number of peen layers (the number of laser hits at ...

Buckling of residually stressed cylindrical tubes under compression

International Journal of Solids and Structures
We evaluate the loss of stability of axially compressed slender and thick-walled tubes subject to a residual stress distribution. The nonlinear theory of elasticity, when used to analyze the underlying deformation, shows that the residual stress induces preferred directions in the reference configuration. The incremental theory, given in Stroh form, is

The effect of cutting speed on residual stresses when orthogonal cutting TC4

EPJ Web of Conferences, 2015
As one of the most important parameters in mental cutting, cutting speed has a significant influence on residual stress. Finite element method and experiment method are used to study the relationship between cutting speed and residual stress when ...

Effect of Residual Stress in Surface Layer on Plastic Yield Inception

Applied Sciences, 2022
This study aimed to acquire a comprehensive explanation on how the residual stress in the surface layer affects the contact behavior of solids. Plastic yield inception of residual stressed surface layer/substrate system during contact is simulated using ...

Surface preparation for residual stress measurement of an accelerated corrosion tested welded marine steel [PDF]

, 2015
Residual stress measurement is often required for the assessment of structural integrity of components. Measurement of residual stress in corrosion tested specimens is challenging owing to the difficulty of accessing the surface because of the rust layer.

Mechanism of Creation of Compressive Residual Stress by Shot Peening.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1997
Abstract In order to clarify the mechanism of the creation of compressive residual stress by shot peening, a static compression test and a dynamic impact test using a single steel ball against a flat steel plate were carried out. In the static compression test, compression residual stress was created near the center of the ball indentation mark ...

RESEARCH ON SHOT STRESS RELAXATION MODEL OF2024-T351 ALUMINUM ALLOY

Jixie qiangdu, 2021
The residual compressive stress field introduced by shot peening can effectively improve the fatigue performance of the component, but decrease of the residual compressive stress cased by the cycle stress relaxation, thereby reducing the gain effect of ...

Residual compressive surface stress increases the bending strength of dental zirconia [PDF]

Dental Materials, 2017
To assess the influence of surface treatment and thermal annealing on the four-point bending strength of two ground dental zirconia grades.Fully-sintered zirconia specimens (4.0×3.0×45.0mm3) of Y-TZP zirconia (LAVA Plus, 3M ESPE) and Y-TZP/Al2O3 zirconia (ZirTough, Kuraray Noritake) were subjected to four surface treatments: (1) 'GROUND': all surfaces ...
