Importance of considering a material micro-failure criterion in the numerical modelling of the shot peening process applied to parabolic leaf springs
(LATIN AMER J SOLIDS STRUCTURES, 2010)
Shot peening is a cold-working mechanical process in which a shot stream is propelled against a component surface. Its purpose is to introduce compressive residual stresses on component surfaces for increasing the fatigue ...
Investigation of residual stress, stress relaxation and work hardening effects induced by shot peening on the fatigue life of AA 6005-T6 aluminum alloy
(2019-01-01)
Fatigue strength improvement of mechanical components is one of the most challenging problems in engineering. One of the known ways to improve fatigue life is by using the shot peening process. However, it is complex to ...
Evaluation of WC-10Ni thermal spray coating with shot peening on the fatigue strength of AISI 4340 steel
(Elsevier B.V., 2010-01-01)
Fatigue failure is a result of a crack initiation and propagation, in consequence of a cyclical load. In aeronautical components as landing gear the fatigue strength is an important parameter to be considered in project, ...
Evaluation of shot peening on the fatigue strength of anodized Ti-6Al-4V alloy
(ABM, ABC, ABPol, 2006-03-01)
The increasingly design requirements for modern engineering applications resulted in the development of new materials with improved mechanical properties. Low density, combined with excellent weight/strength ratio as well ...

Study of fatigue in AISI 4340 steel with different microstructural conditions, submitted to a surface treatment of shot peening
(2016-01-01)
The AISI 4340 steel has been largely employed for structural purposes, which requires resistance levels with yield strength above 1400 MPa and it attains high levels of resistance in dual phase, bainitic or martensitic ...
Effects of nitriding and shot peening treatments and stress concentration on the fatigue strength of AISI 4340 steel
(2001-01-01)
Nitriding is a thermochemical surface treatment applied to improve the fatigue and wear resistances of mechanical components. Shot peening is a cold work process in which small spheres impact the surface of a piece, producing ...
Effects of laser shock processing and shot peening on 253 MA austenitic stainless steel and their consequences on fatigue properties
(Elsevier, 2020-02)
A comparative study of the influence of laser shock peening without coating (LSPwC) and shot peening (SP) treatments on the low cycle fatigue life of 253 MA austenitic stainless steel was investigated. LSPwC treatments ...
