The objective of this effort is to assess the feasibility of a novel modeling and simulation framework to predict the performance of AM parts such that simulations could be used to reduce the amount of qualification testing currently necessary for part acceptance by the Navy. The effort will adapt ATA’s hybrid modeling approach, which combines physics-based simulation and data science methods for interrogating available test data, to characterize a representative part selected by the project team as a demonstration of a modeling process that is robust and easily adaptable to changes in the part geometry, AM process parameters, and material properties. ATA has implemented an analogous simulation workflow for advanced composite materials in a software package known as COMPAS. This work will leverage the existing COMPAS modules as a starting point for the AM simulation workflow.
