  • Investigations into Ductile Fracture and Deformation of Metals Under Combined Quasistatic Loading and Under Extremely Highrate Compressive Impact Loading
    Investigations into Ductile Fracture and Deformation of Metals Under Combined Quasi-static Loading and Under Extremely High-rate Compressive Impact Loading
    Spulak, Nathan
    2020-10-01 | PDF
    Materials experiencing impact loading deform under complex three dimensional states of stress and at high strain rates. Accurately simulating impact events using finite element modeling requires material models capable of depicting the material behavior under these same conditions. In order to create accurate material models, this material behavior ...
  • FullField Measurement of the TaylorQuinney Coefficient in Tension Tests of Ti6Al4V Aluminum 2024T351 and Inconel 718 at Various Strain Rates
    Full-Field Measurement of the Taylor-Quinney Coefficient in Tension Tests of Ti-6Al-4V, Aluminum 2024-T351, and Inconel 718 at Various Strain Rates
    Smith, Jared
    2020-10-01 | PDF
    During plastic deformation of metals only a portion of the plastic work done on the material is expended to modify its physical properties while the remaining energy is converted to heat. The associated rise in temperature during deformation can affect the mechanical response of the material (e.g. strain hardening, thermal softening, precipitating ...
  • Aircraft Rescue and Firefighting Strategies and Tactical Considerations for New Large Aircraft Update
    Aircraft Rescue and Firefighting Strategies and Tactical Considerations for New Large Aircraft: Update
    Kreckie, Jack
    2020-09-01 | PDF
    The evolution of aircraft design and construction has brought about new challenges to Aircraft Rescue and Firefighting (ARFF) personnel. The New Large Aircraft (NLA) entering the market have introduced increased passenger capacities, fuel loads, hydraulic pressures, and the use of advance composite materials. The most significant change is the intr ...
