The quantification of fatigue crack initiators in aluminium alloy 7050‐T7451 using quantitative fractography

Simon A. Barter

This paper aims to present some aspects associated with the life prediction of structures with fatigue cracks growing from small natural discontinuities in aluminium alloy…

Transient thermo‐elastic disturbances in a visco‐elastic semi‐space due to moving internal heat source

Kh. Lotfy

This paper aims to investigate the transient disturbances created by an internal line heat source that suddenly starts moving uniformly inside a visco‐elastic half‐space.

Improvement of fatigue limit by shot peening for high‐strength steel containing a crack‐like surface defect

Koji Takahashi, Toshihiko Amano, Kotoji Ando, Fumio Takahashi

The paper's aim is to investigate the effects of shot peening (SP) on the bending fatigue limit of high‐strength steel containing an artificial semi‐circular slit.

Automated overlays for laser peening

Peter A. Gaydos, Jeff L. Dulaney

Sacrificial opaque overlays used in laser peening provide optimal processing and protect the surface of the part being processed from thermal damage from the laser pulses…

Use of an orthogonal array based on the Kriging model to maximize the fatigue life of a turbine blade

Kwang‐Ki Lee, Kwon‐Hee Lee, Seung‐Ho Han

Approximation techniques were used instead of expensive computing analysis in a traditional parametric design optimization of a complex system. A Kriging meta‐model was utilized…

Laser cladding as a potential repair technology for damaged aircraft components

Qianchu Liu, Madabhushi Janardhana, Bruce Hinton, Milan Brandt, Khan Sharp

The purpose of this paper is to demonstrate the preliminary work on using laser cladding technology for the restoration of structural integrity.

Application of laser peening without coating on steel welded joints

Yoshihiro Sakino, Yuji Sano, You‐Chul Kim

Laser peening without coating (LPwC) is an innovative surface enhancement technology for introducing compressive residual stress in metallic materials. The purpose of this study…

Influence of mosaic patterns on the structural integrity of filament wound composite pressure vessels

Haris Hameed Mian, Hammad Rahman

Filament wound pressure vessels have a characteristic pattern observed in their helical layers. These are mosaic‐shaped patterns and affect the layer structural behavior. The…

Bending fatigue strengths/limits of smooth specimens with and without surface‐enhanced layer of aeronautical metallic alloys

Yu‐Kui Gao

The purpose of this paper is to estimate the bending fatigue strengths/limits of smooth specimens and to quantitatively analyze the effects of residual stresses caused by surface…
