Autor: S. Shademan, Wole Soboyejo, V. Sinha, Alfred B.O. Soboyejo

Publikováno v: Mechanics of Materials. 36:161-175

This article examines the combined effects of colony microstructure and stress ratio on long fatigue crack growth in Ti–6Al–4V. The fatigue crack growth rates are compared in lamellar microstructures with fine and coarse lath dimensions produced

An investigation of short fatigue crack growth in Ti–6Al–4V with colony microstructures

Autor: S. Shademan, Wole Soboyejo

Publikováno v: Materials Science and Engineering: A. 335:116-127

This paper presents the results of an experimental study of the growth of two-dimensional, short fatigue cracks, in Ti–6Al–4V with well-controlled colony microstructures. The underlying crack/microstructure interactions associated with anomalous

A physically-based model for the prediction of long fatigue crack growth in Ti–6Al–4V

Autor: Wole Soboyejo, S. Shademan, Alfred B.O. Soboyejo, John F. Knott

Publikováno v: Materials Science and Engineering: A. 315:1-10

A physically-based model is presented for the prediction of fatigue crack growth in Ti–6Al–4V. The model assumes that the crack extension per cycle is directly proportional to the change in the crack-tip opening displacement, during cyclic loadin

A multiparameter approach to the prediction of fatigue crack growth in metallic materials

Autor: Alfred B.O. Soboyejo, S. Shademan, M. A. Foster, Wole Soboyejo, Noriko Katsube

Publikováno v: Fatigue & Fracture of Engineering Materials & Structures. 24:225-242

A multiparameter approach is proposed for the characterization of fatigue crack growth in metallic materials. The model assesses the combined effects of identifiable multiple variables that can contribute to fatigue crack growth. Mathematical express

Statistical Modeling of Microstructural Effects on Fatigue Behavior of α/β Titanium Alloys

Autor: S. Shademan, V. Sinha, Alfred B.O. Soboyejo, Winston O. Soboyejo

Publikováno v: Key Engineering Materials. 200:1-30

This paper presents the results of combined experimental and theoretical studies of the effects of colony microstructure on fatigue crack growth in Ti-6Al-4V. Colony microstructures with controlled lath widths and colony sizes are produced by control
