  • Back to Basics: Coverage
  • Year: 2021, Source: The Shot Peener magazine, Vol 35, Issue 3, Summer 2021
  • INTRODUCTION Coverage and peening intensity are the two major properties for peened components that have to be both measured and controlled. As with all definitions “The Devil is in the Detail...

  • Back to Basics: Peening Intensity
  • Year: 2021, Source: The Shot Peener magazine, Vol 35, Issue 2, Spring 2021
  • INTRODUCTION Peening Intensity and Coverage are our two main shotpeening parameters. As such, they cover separate aspects of shot peening. Coverage will be the subject of the next article in t...

  • Back to Basics: The “Magic Skin”
  • Year: 2021, Source: The Shot Peener magazine, Vol 35, Issue 1, Winter 2021
  • INTRODUCTION The whole point of shot peening is to improve the service life of industrial components. Peening achieves this aim by inducing a “magic skin” into the components. This skin is a t...

  • Year: 2020, Source: The Shot Peener magazine, Vol 34, Issue 4, Fall 2020
  • INTRODUCTION The aim of this mini-series is to cover the basic scientific principles of shot peening. Fundamental principles are presented together with relevant theoretical explanations. You ...

  • Back to Basics: Shot Velocity
  • Year: 2020, Source: The Shot Peener magazine, Vol 34, Issue 3, Summer 2020
  • INTRODUCTION The aim of this mini-series is to cover the basic scientific principles of shot peening. Fundamental principles are presented together with relevant theoretical explanations. Shot par...

  • Back to Basics: Shot Particles
  • Year: 2020, Source: The Shot Peener magazine, Vol 34, Issue 2, Spring 2020
  • INTRODUCTION The aim of this mini-series is to cover the basic scientific principles of shot peening. Fundamental principles are presented together with relevant theoretical explanations. Shot...

  • The Appliance of Science
  • Year: 2020, Source: The Shot Peener magazine, Vol 34, Issue 1, Winter 2020
  • INTRODUCTION The following is a quotation from a previous article in this series: “Science is almost always able to provide answers to questions about observed phenomena. Consider as exampl...

  • Coverage Science
  • Year: 2019, Source: The Shot Peener magazine, Vol 33, Issue 4, Fall 2019
  • INTRODUCTION Science is almost always able to provide answers to questions about observed phenomena. Consider as examples: “Why are snowflakes sometimes large and sometimes small?”, “Why ...

  • Hardness Matters
  • Year: 2019, Source: The Shot Peener magazine, Vol 33, Issue 3, Summer 2019
  • INTRODUCTION Hardness, for shot peeners, is resistance to localized plastic deformation induced by impacting shot particles. We therefore have two areas of interest: the hardness of the compone...

  • The Solver Story An Autobiography
  • Year: 2019, Source: The Shot Peener magazine, Vol 33, Issue 2, Spring 2019
  • INTRODUCTION: Many years ago Jack Champaigne asked me if I could write a computer program that would determine peening intensity quantitatively. This was to be an alternative to the subjective m...

  • Metals are Alive!
  • Year: 2019, Source: The Shot Peener magazine, Vol 33, Issue 1, Winter 2019
  • INTRODUCTION Metallic objects abound in shot peening—steel shot, Almen strips, nozzles, wheels, etc. The metals used are alive! Essentially metals are made up of a regular framework of vibrati...

  • The Curvature of Peened Almen Strips and Its Applications
  • Year: 2018, Source: The Shot Peener magazine, Vol 32, Issue 4, Fall 2018
  • This article embraces an analysis of why peened Almen strips have this parabolic shape together with experimental evidence and a consideration of its practical significance. Understanding the cause...

  • Almen Strip Quality
  • Year: 2018, Source: The Shot Peener magazine, Vol 32, Issue 3, Summer 2018
  • INTRODUCTION: Shot peeners are required to declare values of peening intensity derived at prescribed intervals. These values depend, to a significant extent, on the quality of the Almen strips th...

  • Component Distortion An Overview
  • Year: 2018, Source: The Shot Peener magazine, Vol 32, Issue 2, Spring 2018
  • INTRODUCTION: Every shot peener distorts components—if only in the form of Almen strips. They would be useless if they didn’t distort! Distortion is caused by a combination of plastic deformati...

David Kirk

Born into a multi-generational steelworking family — his grandfather was a Head Roller and his father was an Open-Hearth steelmaker and also a part-time lecturer at Rotherham Technical College — David won a scholarship to a local grammar school. Grammar school success secured three scholarships that took him to Birmingham University to read Industrial Metallurgy. He was the first member of his family to attend university. After graduation, a Department of Science scholarship allowed research that finished with a doctorate for a thesis entitled "The Hot Working of Metals."

First employment as a Research Fellow at Birmingham University was followed by a short period as a Senior Research Metallurgist at the International Nickel Company's Research Laboratory in Birmingham. David then joined Coventry University as a Senior Lecturer in Metallurgy. At Coventry University, he was promoted to Principal Lecturer in Metallurgy and then Chairman of the School of Materials. Initial research activity centered on X-ray residual stress measurement which prompted him to establish Coventry Science Consultants Ltd. This was followed by his installation of a shot-peening research laboratory at the University with active encouragement and advice by the late Jack Plaster.

Upon retirement, David was first appointed as a Visiting Research Fellow and is now Visiting Professor of Materials at Coventry University. David has, after retirement, published some 70 research papers and articles on shot peening and residual stresses. Following his organization of the International Conference on Shot Peening in Oxford, he was elected Chairman of the International Scientific Committee for Shot Peening and he was subsequently elected to be a Life member. David was awarded The Shot Peener of the Year award in 2001 for his significant contributions to the advancement of shot peening.
