This work aims at modelling the mechanical behaviour of inorganically-bound core materials. In this article, the mechanical material parameters for inorganically-bound core materials for various binder amounts and temperatures are determined. Specifically, the influence of the binder amount on the elastic properties and the Mohr–Coulomb parameters of the sand cores is studied. Furthermore, the hardening process of the cores after the core shooting is analysed regarding its influence on the material parameters. The goal is to characterise inorganically-bound core materials for handling simulations. This material model is implemented into a finite element simulation to predict core failure in industrial handling processes. This finite-element model is validated with a complex water jacket core geometry and different load cases, which are derived from real industrial handling processes.
