Summary of B 01

Selective laser melting is a process involving several length scales, fluid and solid mechanics. Project B01 provides a model and related computational framework for simulation of the SLM process, from the micro-scale (powder bed) to the meso- scale (mm range). To that end, local melting, flow, and solidification are simulated using the Lattice-Boltzmann method (LBM), considering more and more physical phenomena. By coupling the LB simulation to a solid mechanics Finite Element (FE) simulation residual stresses are predicted. Upscaling leads to effective material properties and state of material for use in macroscopic simulations (e.g. C01).
