Abstract

In this contribution the mesoscopic material behavior of columnar grained Inconel 718 is modeled with a gradient enhanced crystal plasticity formulation and simulated by means of Finite Elements. A Voronoi tessellation based method is used to model the grain structure. On the mesoscale, the thermo‐mechanical behavior is modeled using a thermal gradient‐crystal‐plasticity model, allowing for relative misorientations on the grain boundaries. Computational homogenization and macroscopic experimental data are used to inversely identify elastic and plastic mesoscopic mechanical parameters. With the homogenized RVE at hand the parameters of a general anisotropic yield criterion for the macro scale are identified.
