For establishing additive layer manufacturing in production technology, an extensive knowledge about the transient physical effects during the manufacturing process is mandatory. In this regard, high process stability for various alloys is realisable, if approaches for the virtual qualification of adequate process parameters by means of a numerical simulation based on the finite element analysis (FEA) are developed. Hence, the presented work contains particular approaches using the FEA for the simulation of transient physical effects within the additive layer manufacturing process. First, a modular simulation system for the analysis of temperatures, deformations and residual stresses is presented. Second, several specific simulation systems are derived, applied and validated based on the modular approach. The configuration of single modules includes the criteria simulation efficiency and accuracy.
