R J H WanhillDr. Wanhill has two Ph.D.s, one in metallurgy from the University of Manchester Institute of Science and Technology, and the second Ph.D, from Delft University of Technology. In 1970 he joined the National Aerospace Laboratory NLR in the Netherlands,and since then has investigated fatigue and fracture of all classes of aerospace alloys. He is co-author of the book "Fracture Mechanics." Since 1994 he has also been investigating fracture phenomena in ancient silver and iron, and has published seven peer-reviewed papers on this topic. He also has a lecture course on ancient silver, prepared for the Netherlands Cultural Heritage Agency and the University of Amsterdam. Dr. Wanhill is now a Principal Research Scientist (emeritus) in the Aerospace Vehicles Division of the NLR. He has recently been working on the analysis of fatigue cracking in GLARE panels from the Airbus 380 MegaLiner Barrel test (presented at ICAF* 2009) and, in collaboration with Simon Barter (Defence Science and Technology Organisation, DSTO, Melbourne), on the use of marker loads for fatigue life assessment, fatigue thresholds in 7075-T7351 aluminium, and the fatigue crack growth properties of high strength alloys (titanium, aluminium) to be used in the JSF.
