Abstract Scope |
As the landscape of large-scale additive manufacturing (AM) quickly advances, integrating materials simulation techniques into the design framework is essential to accelerating development. Simulation enables reduction in process design time and residual stress prediction, plus optimization of programmed deposition paths as well. In this research, finite element analysis (FEA) modeling of both an arc and laser heat source were performed for Nickel-Aluminum-Bronze (NAB) wire deposition. Single-pass scenarios using a range of Goldak and Gaussian heat source dimensions were examined and compared to cross-sectional images of physical builds for verification and validation of the predicted melt pools. Results informed the selection of heat source dimensions for specific thermal scenarios. Additional multi-pass scenarios investigated thermal cycle effects on multi-layer parts, which is essential for understanding microstructural development within large-scale builds. All of the models provided valuable information for optimized processing conditions for large-scale builds of NAB material using wire-based AM techniques. |
