Engineering design methods based on the assumption of crack growth and the application
of fracture mechanics principles are commonly used in aerospace engineering for the …

This paper attempts to compare regular shot peening (RSP) and semi-random shot peening
(SRSP). A characteristic of the first method is that the peening elements hit the treated …

Shot peening (SP) parameters are optimized and their effects on fatigue life are investigated
using a response surface methodology (RSM) for AA7B50-T7751. Three parameters (SP …

Shot peening is a well-known surface treatment method used for fatigue life improvement of
cyclically loaded structural components. Since three main variables are considered in the …

A carbon nanotubes (CNTs)-reinforced Al–Mg–Si alloy composite was made and shot
peened. After shot peening, a compressive residual stress field was generated in shot …

A carbon nanotube (CNT)-reinforced Al matrix composite was fabricated and treated by shot
peening. After shot peening, isotropic compressive residual stress fields were induced in …

Various fields of engineering such as automobile, aerospace and construction industries are
employs Aluminum alloys and its composites due to its high strength to weight ratio. But they …

Aluminum alloys and composites are widely used in the field of aviation due to their high
strength/weight ratio. However, due to their relatively low hardness values, they have poor …

Shot peening treatments with coverages of 100%, 300%, 600%, and 1000% were performed
to investigate the effects of shot peening coverage on the fatigue behavior of a 7B75-T7751 …
