This paper gives a brief overview of published results pertinent to ultrasonic shot peening, a relatively new method to introduce severe plastic deformations in the surface of materials and obtain nanosized grains. Among reported benefits are increased surface hardness and fatigue resistance, and possibility to perform nitriding at lower temperatures ...

Overview of ultrasonic shot peening
Surface Engineering, 2017Ultrasonic shot peening (USP) is acknowledged as an effective surface treatment method to enhance the mechanical performance of materials by inducing compressive residual stress in solid metals and alloys. This article overviews recent researches from our group at Purdue University on the USP in the aspects of modelling the kinetics of the shots ...

Simulation of shot dynamics for ultrasonic shot peening: Effects of process parameters
International Journal of Mechanical Sciences, 2014Ultrasonic shot peening is a pre-stressing process that enhances the life span of mechanical parts. The spheres constituting the shot are set in motion with a sonotrode and impact the treated part to generate a compressive residual stress field, hence increasing fatigue life.

3D Model of Shot Dynamics for Ultrasonic Shot Peening
Materials Science Forum, 2013This paper presents a 3D model that simulates an ultrasonic shot peening (USP) operation, using realistic process parameters and peening setups (part and chamber geometries). By simulating the shot dynamics (shot trajectories and impacts), statistical and spatial data are obtained for the peened component, i.e.

Modelling of Ultrasonic Shot Peening
Volume 6B: Materials and Fabrication, 2015Component manufacturing may induce cold work, residual stresses, microstructure changes and even surface defects. This initial condition is usually ignored in component integrity assessments, but can strongly affect its lifetime. For instance, it is well-known that a rough surface finish associated to the presence of tensile residual stresses may favor

Random Approach to Peening Coverage in Ultrasonic Shot-Peening
Materials and Manufacturing Processes, 1995Abstract The so-called ultrasonic shot-peening is a new process using calibrated peening hard balls motioned by walls vibrating at 20000 Hz. As in conventional shot-peening, a fully peened surface coverage is required tor the process to be efficient. However, it is intricate to determine the coverage ratio experimentally. A statistical approach, issued

Modelling of the Ultrasonic Shot Peening Process
Materials Science Forum, 2005The aim of this work is to reach a better understanding of the ultrasonic shot-peening process and, in particular, the evolution of the shot speed distribution. A simple 1D modelling of the interaction between the shots and the sonotrode is carried out.
