Abstract Scope |
Modeling of hot isostatic pressing (HIP) holds significant potential for enhancing performance while reducing costs in industries such as aviation, power generation, and additive manufacturing. The ability to virtually optimize HIP parameters for achieving complete densification in components of varying sizes and intricate geometries is crucial for expediting process development. However, the success of this modeling approach may depend on addressing various sources of uncertainty, particularly in material behavior.
To address these uncertainties, we conducted a sensitivity analysis to examine how variations in material properties impact the densification model. Our research incorporates General Electric's proprietary tools, including bayesian hybrid modeling (BHM) and intelligent design and analysis of computer experiments (IDACE), in both metamodeling and intelligent sampling frameworks. The results highlight the significant influence of material properties on the densification process in HIP, both as independent main effects and in their interactions, whether second-order or higher. |
