Effect of inclusions on temperature and loading rate dependent strength, deformation and failure behavior (C05)

• Subject Area: Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 169148856

The project is focused on the detailed investigation of the kinetics of the onset of crack growth at non-metallic inclusions as a function of temperature und loading rate. The damaging effect of ductile fracture and cleavage fracture is evaluated separately by analyzing acoustic emissions in-situ. The effect of the spatial distribution and the distribution of size and shape of the non-metallic inclusions on the kinetics of the onset of crack growth and the stable and/or unstable crack propagation is investigated as a function of the crack opening mode.
