Effect of shot peening on fatigue behavior of AISI 4340 in different loading conditions
(2016-01-01)
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 ...
Structural analyzes of the use of residues of tires in reinforced concrete
(2004-12-01)
The search for an adequate destination to the tires without use is a problem for many countries. The use of tire rubber in concrete through the partial substitution of the small aggregate has for objective the withdrawal ...
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 ...
