Dr. Scott Carlson from Lockheed-Martin's Aeronautic Company will give a seminar titled "A Historical Perspective of Metallic Alloy Development and Its Role in Aircraft Structural Integrity" to the interested faculty and stduents at Discovery Park.

Abstract

The history of aircraft design, assembly, usage and repair is intimately connected to the evolution of metallic alloys. Through the application of material science and engineering metallic alloys have played a vital role in expansion of the airplane’s role in both the commercial and military environments. This presentation will provide a structural integrity perspective on the role of metallic materials and how aircraft design paradigms have shaped alloy development and selection for fatigue and fracture critical structural components. This presentation will provide the foundation for a perspective on how our next generation of material scientists and engineers are going to shape the same aircraft structural integrity landscape through advanced alloying, additive manufacturing, and machining processes.

Bio

Dr. Carlson is employed by the Lockheed Martin’s Aeronautic Company in Ft. Worth Texas. At Lockheed Martin, he gets to work in the F-35’s Service Life Analysis group. Within that group he has been assigned to be the focal for the qualification and implementation of advanced Engineered Residual Stress (ERS) processes such as Laser Peening (LP), Cold Expansion (Cx) of critical fastener holes, and shallow peening processes like Needle Peening and Shot Peening for the F-35 program. In that role Dr. Carlson has had the opportunity to help develop, design, test, and analyze the fatigue nucleation and crack growth propagation within the engineered residual stress field imposed by these ERS process. With the F-35 moving full steam into the sustainment phase of its lifecycle. Dr. Carlson currently acts as the Fatigue Test Lead & Residual Stress SME for the F-35 Service Life Team. In that role he is reviewing the current F-35 lifeing methods, in both the strain-life and crack growth regimes. He and his family moved to Texas in 2018 and love the people and the State of Texas. Dr. Carlson earned his BA from Utah State University and his MS and PhD from the University of Utah, under the tutelage of Prof. David W. Hoeppner. He and his wife Catherine are the parents of 8 children, with the oldest now married and attending college at Utah State University and the youngest is 4.
