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 ...
Compressive fatigue in titanium dental implants submitted to fluoride ions action
(2007-07-01)
The aim of this study was to assess the influence of a fluoridated medium on the mechanical properties of an internal hexagon implant-abutment set, by means of compression, mechanical cycling and metallographic characterization ...
Fracture analysis in 5HS carbon composites subjected to pure modes I and II fatigue induced delamination
(2014-01-01)
Interlaminar fracture process in woven composite laminate in general takes place in a nonlinear front propagation when analyzing a 2-D propagation for mode I opening. The nonlinearity is justified by the arresting crack ...
Study of fatigue crack growth in al-mg-si alloys using a predictive model under positive and negative load ratios
(2014-01-01)
The study of fatigue crack growth (FCG) is aimed at residual life estimations in order to apply the damage tolerant criterion. Usual approaches are based on semi-empirical models that consider the stress intensity factor ...
Fatigue crack growth in an Al-Mg-Si alloy under negative load ratio
(2017-01-01)
The usual approaches for Fatigue Crack Growth (FCG) assessment are based on semiempirical models that consider the stress intensity factor range of fracture mechanics, ΔK, as the governing driving force for crack propagation. ...
Fatigue crack growth rate in mode I of a carbon fiber 5HS weave composite laminate processed via RTM
(Trans Tech Publications Ltd, 2014-01-01)
Delamination or crack propagation between plies is a critical issue for structural composites. In viewing this issue and the large application of woven fabrics in structural applications, especially the ones that requires ...
