Abstract:

Physics insight gained from computational modeling and simulation CMS of additive manufacturing AM processes can help facilitate effective multiscalemultifunctional tailoring of AM parts. However, accurately capturing the physics of AM with traditional CMS can be costly with respect to resources and time. The main objective of the work described in this document is to explore projection-based reduced-order modeling PROM as a means to reduce CMS resources and time of the heat-deposition additive manufacturing physics. The presented PROM framework can be deployed to accelerate multi-query settings, as seen in design optimization frameworks for the multiscalemultifunctional tailoring of AM-based parts.
