The laser shock peening (LSP) process using a Q-switched pulsed laser beam for surface
modification has been reviewed. The development of the LSP technique and its numerous …

In recent years, ultrasonic-assisted machining (UAM) has been widely implemented to
improve the performance and element quality of machined products. This paper …

Welding technology has been widely adopted to fabricate structures and components due to
its low cost and easily accessible procedure. However, the welding methods usually impose …

High frequency mechanical impact treatment is observed to increase the fatigue strength of
welded joints. This technique induces compressive residual stresses, increases the local …

A set of ultrasonic burnishing equipment with two different burnishing tips was designed and
manufactured, with which a series of experiments were performed to explore the effects of …

The effects of ultrasonic impact treatment (UIT) on the residual stress within a 45 mm-thick
high-strength steel welded joint were investigated. The internal residual stresses after UIT …

A comprehensive variable amplitude (VA) fatigue testing program and analysis was
performed to address a number of concerns raised regarding the use of impact treatments …

The fatigue damage assessment of welded structures is of critical importance in the design
of many engineering structures. The thermomechanical nature of the welding process leads …

In 2013, a new guideline for the design of high-frequency mechanical impact (HFMI)
treatment was drafted. The proposed design curves were made based on the fatigue data of …

A 304 stainless steel weld overlay pipe was manufactured, and the nickel-base alloy was
applied as the overlay weld. The local region of the pipe was treated using ultrasonic impact …
