Senior Software Application Engineer


Bio


Dr. Dustin brings a pragmatic perspective on composite structure design, manufacture, analysis and test to the CMSC.  His interest in composite materials grew from his love for skiing, biking, and watersports which he developed into a successful career in the aerospace industry.  He has worked in a wide range of areas including:

  • Development of automated vacuum bagging technologies for autoclave processing
  • Adhesive bonding of metallic and composite structure
  • Multi-scale modeling of composite materials
  • Progressive failure analysis of composite structure via advanced non-linear FEA
  • Mechanical and physical test method development
  • Progressive failure analysis method development and validation
  • Advanced non-destructive evaluation including in-situ techniques for identification of failure initiation and mapping failure propagation
  • Composite design allowables including test selection, design and statistical data reduction on tape, fabric, braid, and carbon/glass hybrid material architectures   

Dr. Dustin holds a M.S.E. and Ph.D. from Purdue University’s School of Aeronautics and Astronautics and a B.S. in Mechanical Engineering from Brigham Young University.  He serves on the Materials Technical Committee for the AIAA concentrating primarily on ICME initiatives.  He holds a US patent in the area of composite material testing and has multiple pending patent applications in addition to his conference proceedings and other technical publications. 
Upon finishing his graduate work, Dr. Dustin worked in the Structural Analysis group within Boeing Research & Technology where he was the Principle Investigator of multiple Internal R&D initiatives focused on validating progressive failure analysis methods for composite materials and development of test methods to generate data for method validation.  He secured million dollar plus budgets composed of internal and external funding to accomplish the initiatives. 
Prior to joining the CMSC, he worked in the Composite Materials Behavior group with GE-Aviation primarily tasked with the design and execution of the design allowables program for the first ever carbon/glass hybrid critical structure, the GE9X fan blade.  Additionally, Dr. Dustin managed multiple material characterization programs for a wide variety of commercial and military applications.  He also was a primary contributor to the AFRL funded ICM2 program and the NASA funded Advanced Composite Project providing both analysis and testing expertise.
