Project area C
The project area C "Modeling" deals with the modeling of damage of sheeted and bar materials and with the description of recovery phases for the reduction of material damage.
In the first funding period (1st to 4th research year), fundamental model approaches will be developed and verified in close cooperation with projects of project areas A "Process technology" and B "Characterization". Project C01 focuses on the prediction of the operating behavior of semi-finished products and the quantification of failure-triggering microstructural defects. An anisotropic macroscopic material model for ductile damage is being investigated in project C02. In cooperation with the service project S01, this model will be made accessible to project area A. There, it can be used for process simulation and design. The primary goal of project C03 is to understand the interactions between local hardening and softening in the vicinity of the interface matrix inclusion and damage initiation at the interface and to develop a coupled model of hardening/softening and damage on this basis. A crystal plasticity-based modeling approach, which is directly coupled with a damage model, is being developed in project C04. Optimization problems, such as process design to minimize damage and maximize the operating time, are the subject of project C05.
