Uncertainty Propagation Through Solidification Process Models (Matthew Krane, Purdue)
Complex solidification processes are often simulated to gain insight into physical phenomena that cannot be experimentally observed. These predictions depend on alloy, process, and numerical parameters which contain inherit uncertainties due to experimental measurements or model assumptions. The lack of precise knowledge about the values of these simulation inputs give rise to uncertainty in the model outputs of interest. In this talk, such propagation of uncertainty through the models of solidification is evaluated in industrial applications, including metal remelting processes and laser powder bed fusion. In each case, the solidification model is used in a framework for uncertainty quantification (UQ) analysis.
Bio: Dr. Krane is a Professor of Materials Engineering at Purdue University and a member of the Purdue Center for Metal Casting Research. His research is on design, development, and modeling of materials processes, particularly the solidification processing of metal alloys. He has been with Purdue Materials Engineering since 1996, but his education is three degrees in mechanical engineering (Cornell, BS, ’86; U. Pennsylvania, MS, ’89; Purdue, PhD, ’96), with a concentration in heat transfer and fluid flow.
