| Abstract Scope |
The present study is part of an integrated computational materials engineering (ICME) thrust to expand the use of computational simulations for additive manufacturing (AM) components within shipbuilding. Finite element analysis (FEA)-based tools have been developed to simulate the entire build process, including distortion and residual stress. To address this, recently developed computational tools are under a validation investigation for laser powder-bed fusion (L-PBF) builds. The on-going investigation includes physical validation of unique, complex AM-enabled parts to understand how modification of the process can improve build efficiency and reduce instances of failed builds. Additionally, the thermal modeling of the build process will likely influence the developed microstructure, thereby giving insight into how to modify build processes in order to obtain designed alloy systems. The project goal is to validate the computational tools to determine best practices for insertion of computational AM simulation into shipyard fabrication. |
