Dual-phase steel shows a pronounced structure-property correlation, caused by its internal structure consisting of a soft ferrite matrix and embedded hard martensite regions. Due to its high strength combined with high ductility, dual-phase steel is particularly suitable for energy-absorbing and strength-relevant sheet metal applications, but its use as heavy plate is also desirable. Due to the complex microstructure, microstructure-based simulation is essential for a realistic simulation of the mechanical properties of dual-phase steel. This paper describes two important points for the microstructure-based simulation of dual-phase steel. First a method for the straightforward experimental estimation of the RVE size based on hardness measurements prior to tomography preparation is presented and evaluated. Secondly, a method for the efficient meshing of these microstructures, based on material definition at the integration points of a finite element model, is developed. |
