AF Research Laboratory materials engineer receives prestigious award Published May 11, 2016 By Holly Jordan Air Force Research Laboratory Materials and Manufacturing Directorate WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFNS) -- An engineer with the Air Force Research Laboratory Materials and Manufacturing Directorate was honored with the American Society for Testing and Materials International Award of Merit at a ceremony May 3 in San Antonio for his work in the area of metals fatigue and fracture.Dr. Andrew Rosenberger, a recognized expert in the area of mechanical behavior of materials, leads the Engine Organic Life Assessment program, an effort to demonstrate the ability to organically determine and extend the useful life of F100-220 engine fracture-critical components using existing data.Rosenberger also applies his expertise to the study of fatigue and crack growth in high-temperature metals found in gas turbine engines. He has assisted numerous Air Force engine program offices to help solve issues that affect the performance or durability of fracture-critical components.ASTM International is a largely volunteer organization that develops and delivers standards used around the world to improve product quality and build consumer confidence. The award of merit is the highest award bestowed upon an individual member, and award recipients also receive the honorary title of ASTM fellow."It is a tremendous honor to receive this award," Rosenberger said. "Research and standards in this area are vital to the future of the Air Force as we seek to improve our methods of assessing and determining fatigue durability and damage tolerance of turbine engines and aircraft structures."The honor is bestowed to less than two-tenths of 1 percent of the society's active membership annually.
