Projekt
Phase Field Modeling of Transformation and Failure Mechanisms in the Vicinity of Surface (A05)
Subject Area
Mechanics
Term
from 2011 to 2023
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 172116086
The goal of project A05 is a macroscopic and phenomenological model for phase transformations and failure mechanisms. A thermodynamically consistent formulation for the modelling of the phase transformation is employed, where plasticity, hardening and volume fraction of the transformed material are considered as internal variables. The modelling will include a coupling between plasticity and phase transformation. Tensile and torsion tests of TRIP and Cr-Ni steels allow to identify important material parameters. Further, the model is extended by introducing a scalar damage variable as well as considering cyclic loading. In terms of verification high cycle fatigue testing and tribology testing are used.
