Notes on New Physical & Hybrid Modelling Trends for Material Process Simulations

Abstract

Abstract The more innovative production techniques for faster, cheaper and better-quality parts have encouraged more ambitious research works on numerical simulation of material & processes designs. A brief description of such ambitious work has been presented in this paper where some explanations of scientific and technical basis for some of latest physical & hybrid trends in material process simulations are concisely discussed. The topics of combining numerical, analytical and data-driven schemes along with evolving & dynamic mesh methods for simulation of dynamic material processes like casting, extrusion, Additive Manufacturing (AM) are also briskly described. Other trends like multi-scale and multi-resolution schemes for solidification (multi-phasing) and cooling applications are addressed, and fresh ideas of hybrid physical-data driven models (using Genetically Algorithm Symbolic Regression, GASR) and their applications are tersely presented. The effects of increasing computational power on hybrid multi-scale modelling and its implications for future of material modellings are also presented shortly. For the short paper herein, it has not been intended to publish the detailed results of new simulation technologies, rather it is focused on describing some new physical & hybrid trends for future of material process simulations.
