Describing fatigue crack growth and load ratio effects in Al 2524 T3 alloy with an enhanced exponential model
(Elsevier B.V., 2012-08-01)
The fatigue crack behavior in metals and alloys under constant amplitude test conditions is usually described by relationships between the crack growth rate da/dN and the stress intensity factor range Delta K. In the present ...

Subcritical fatigue in fuse networks
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETYMULHOUSE, 2012)
We obtain the Paris law of fatigue crack propagation in a fuse network model where the accumulated damage in each resistor increases with time as a power law of the local current amplitude. When a resistor reaches its ...
Subcritical crack growth in porcelains, glass-ceramics, and glass-infiltrated alumina composite for dental restorations
(SPRINGER, 2009)
The objective was to compare fracture toughness (K(Ic)), stress corrosion susceptibility coefficient (n), and stress intensity factor threshold for crack propagation (K(I0)) of two porcelains [VM7/Vita (V) and d.Sign/Ivoclar ...

Crescimento super e subcrítico de trincas em vidros e vitrocerâmicos analisado via indentacão
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2012-07-02)
In this dissertation we quantified properties that may better describe the mechanical behaviour of different glasses and glass-ceramics of the Na2O-CaO-SiO2-P2O5 system, based on the Biosilicate®chemical composition developed ...
Influence of nickel on the susceptibility to corrosion fatigue of duplex stainless steel welds
(Elsevier, 2001-06)
The object of this work is to analyse the mechanisms of corrosion fatigue and to study the influence of Nickel on the susceptibility to corrosion fatigue in welded Duplex stainless steels. A ‘Ferralium 255’ type cast Duplex ...
Efeito dos diferentes tratamentos de superfície na resistência à fadiga do dissilicato de lítio
(Universidade Estadual Paulista (Unesp), 2016-06-17)
Este estudo avaliou o crescimento subcrítico de trincas de uma cerâmica à base de dissilicato de lítio, levando em consideração dois tipos de tratamento de superfície. Blocos de dissilicato de lítio parcialmente cristalizados, ...
Conceptos de probabilidad y estadística en análisis de fallas de componentes mecánicos
(Universidad Nacional de Colombia - Facultad de Ingeniería, 1996)
Cuando se presenta una falla en un componente mecánico, de alguna manera, la carga aplicada se hace igual o mayor a la carga de falla en el momento que esta se produce. Teniendo en cuenta este principio y considerando la ...
