  • Continuous Measurement Versus Intermittent Indication of Peening Intensity Curves
  • Year: 2011, Source: The Shot Peener magazine, Vol 25 / Issue 4, Fall 2011
  • Academic Study by Dr. David Kirk INTRODUCTION Peening intensity curves are of vital importance for effective shot peening. They can be either continuously measured or intermittently indicated. The...

  • Variability of a Shot Stream
  • Year: 2011, Source: The Shot Peener magazine, Vol 25 / Issue 3, Summer 2011
  • Academic Study by Dr. David Kirk INTRODUCTION A particular shot stream should always be regarded as a combination of shot particles carried along in a stream of fluid. The fluid is normally air but ...

  • Properties of Carbon Steel Shot
  • Year: 2011, Source: The Shot Peener magazine, Vol 25 / Issue 2, Spring 2011
  • Academic Study INTRODUCTION Most shot peening is carried out using carbon steel shot. This shot is produced either by casting directly to almost spherical shapes or by cutting lengths of wire and p...

  • Inaccuracy and Variability of Shot Peening Measurements
  • Year: 2011, Source: The Shot Peener magazine, Vol 25 / Issue 1, Winter 2011
  • Academic Study by Dr. David Kirk NTRODUCTION Every measurement ever made of a shot peening parameter has been inaccurate ...

  • Two Strip Setting-Up and Verification Program for Peening Intensity
  • Year: 2010, Source: The Shot Peener magazine, Vol 24 / Issue 4, Fall 2010
  • Academic Study INTRODUCTION The most accurate method of estimating peening intensity is to produce and analyze a saturation curve constructed from the arc heights of four (or preferably more) peened...

  • Peening Indent Dimensions
  • Year: 2010, Source: The Shot Peener magazine, Vol 24 / Issue 3, Summer 2010
  • Academic Study INTRODUCTION Indent size really matters! It has a direct effect on both peening intensity and coverage. Peening intensity is directly proportional to the size of the indents. Coverag...

  • Accurary of Declared Peening Intensity Values
  • Year: 2010, Source: The Shot Peener magazine, Vol 24 / Issue 2, Spring 2010
  • Academic Study by Dr. David Kirk INTRODUCTION Peening intensity is the arc height of one particular point on a simulated saturation curve that is declared as meeting specification requirements. Thre...

  • Meaning, Measurement Philosophy and Verification of
  • Year: 2010, Source: The Shot Peener magazine, Vol 24 / Issue 1, Winter 2010
  • “Peening intensity” is the depth-inducing capability of a shot stream. Shot peening causes plastic deformation of component surfaces - inducing compressive residual stress in the deformed surface ...

  • Strip Factors Influencing Almen Arc Height
  • Year: 2009, Source: The Shot Peener magazine, Vol 23 / Issue 4, Fall 2009
  • INTRODUCTION Almen arc height is the deflection of the center of an Almen strip. This deflection, when caused by bombarding one face of the strip with high velocity shot particles, is used as a meas...

  • Non-Uniformity of Shot Peening Coverage
  • Year: 2009, Source: The Shot Peener magazine, Vol 23 / Issue 3, Summer 2009
  • Academic Study by Dr. David Kirk INTRODUCTION It would be very desirable if shot-peened components could have a uniform coverage of indentations. Unfortunately this is impossible to achieve. As a sh...

  • Shot Peening Coverage: Prediction and Control
  • Year: 2009, Source: The Shot Peener magazine, Vol 23 / Issue 2, Spring 2009
  • INTRODUCTION For both peeners and customers, coverage is of vital importance. Our central problem is to be able to predict and control coverage so as to reach a specified level. It is not sufficient...

  • Size and Variability of Cast Steel Shot Particles
  • Year: 2009, Source: The Shot Peener magazine, Vol 23 / Issue 1, Winter 2009
  • Academic Study Dr. David Kirk INTRODUCTION Size is probably the most important property of cast steel shot. It affects saturation intensity, coverage rate and depth of work-hardened layer. Any varia...

  • External Characteristics of Shot Peened Surfaces
  • Year: 2008, Source: The Shot Peener magazine, Vol 22 / Issue 4, Fall 2008
  • Academic Study INTRODUCTION Shot peened components have two important external characteristics. These are: SURFACE ROUGHNESS and DIMPLE COVERAGE. Surface roughness depends mainly upon the size of sh...

  • Control of Peened Layer Development
  • Year: 2008, Source: The Shot Peener magazine, Vol 22, / Issue 3, Summer 2008
  • Academic Study Dr. David Kirk INTRODUCTION The prime objective with shot peening is to induce a well-developed protective surface layer of plastically-deformed material. This layer has two important...

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.
