Abstract Scope |
A brief review of four decade journey to modeling thermo-mechanical processes is a perfect way to acknowledge and thank the four stalwarts of their tremendous contribution to processing science and ICME. From there, this presentation delves into recent advances in various areas including meshing, handling multiple material groups, solvers, anisotropic modeling, DOE sensitivity analysis, optimization techniques and data analytics. These recent developments have helped to effectively model additive manufacturing, solid state welding and shot peening processes and few examples of these modeling applications will be presented. Enhancements to multi-scale microstructure modeling capabilities will be demonstrated. The impact of variabilities and uncertainties associated with processing conditions, boundary conditions and material properties on the evolution of microstructure during thermo-mechanical processing will be presented. Finally, a brief overview and application of data analytics tools to establish surrogate models will be demonstrated. |
