  1. Fork Reading Duncan Slater MICFor

  2. Yet another of my ‘Fork Talks’ Thank you for having me back!  Again!! Today, I want to report my research progress So here comes the ‘sciency bit’…

  3. Presentation Summary • Experiments and their outcomes • Planned experimental programme • Reading forks • Your tea! 

  4. Experiment Oneaka « Genghis Khan »

  5. Experiment OneOutcome No. 1

  6. Experiment OneOutcome No. 2

  7. Experiment OneOutcome No. 2

  8. Experiment OneOutcome No. 2

  9. Experiment OneOutcome No. 3

  10. Experiment Twoaka « Driller Killer »

  11. Experiment TwoOutcome No. 1

  12. Experiment TwoOutcome No. 2 Forkwood was 17.5% denser than stemwood in hazel

  13. Experiment Threeaka « X-Ray Vision »

  14. Experiment ThreeOutcome 1:

  15. Experiment ThreeOutcome 1

  16. Experiment ThreeOutcome 2

  17. Experiment Fouraka « Bristol City »

  18. Experiment FourMethodology

  19. Experiment FourOutcome The forks of modern clones were significantly weaker due to their V shape

  20. Experiment Fiveaka « FEA – Forking Electronic Answer »

  21. Experiment FiveExpected outcome Stronger Weaker

  22. Experiment Sixaka « Bark worse than Bite»

  23. Experiment SixExpected outcome Forks with bark inclusions vary in strength, and are not necessarily a flaw Stronger Weaker

  24. Planned Experimental Programme • Constructing a 3D “electronic fork” (FEA) • Measuring oscillations of bifurcations in the wind with laser sensors • Testing the effects of bracing and cracking • Investigating environmental factors that affect the development of bark inclusions • Measuring the pre-strains found at forks • Testing the ‘Axiom of Uniform Stress’ in relation to fork oscillations using strain gauges

  25. Reading Forks Although the topic is complex, I hope to be able to simplify the findings for the end-users: tree surveyors It is likely through examining the fork’s morphology and position, an educated judgement could be made on its risk of failure

  26. Remodelling

  27. The Write-Up! • First paper in Arb Journal, 2010 • Two submitted to journals currently • Two more submissions by end of 2012 • Overall target is 12 papers from PhD

  28. Acknowledgments • Dr. Roland Ennos – supervisor • Myerscough College – sponsor • Dr. Robert Bradley – MXIF • Mike Carswell – supplier of hazel forks • BSc (Hons) students: Joe Barnes, Mat Dumelow, Claire Harbinson, Sam Turner and Ian Williams

  29. Your tea ! On time, as promised! 
