U.S. Army Combat Capabilities Development Command (DEVCOM) Analysis Center (DAC) RelTools Dashboard
Reliability is the probability that an item will perform its intended function for a specified period under stated conditions. It has a significant impact on operating and sustainment costs within the U.S. Department of Defense (DoD), which typically represent 70% of the program’s total life-cycle costs [1].
A Surrogate Model to Quantify Uncertainty in Thermal Protection Systems for Hypersonic Weapons
Modeling and simulation are key for the iterative development of thermal protection systems (TPS’s) for hypersonic weapons. In this work, the temperature-dependent flexural strength (FS) of α-SiC ceramic is predicted given Young’s modulus, Poisson’s ratio, and temperature. An artificial neural network (ANN) surrogate model is created to retain property-performance prediction while increasing computation speed.
Revolutionizing Naval Logistics: The Challenges and Prospect of Metal Additive Manufacturing on U.S. Navy Ships
In 2022, the U.S. Navy installed the first-ever permanent metal AM machine aboard a U.S. naval vessel. This technology is projected to be groundbreaking by reducing resupply logistics and diminishing obsolescence: “For the Navy, the greatest immediate potential is in the less-exotic field of logistics” [1].
