Thermo-Mechanical Fatigue in Cast Iron: Multi-Scale Physical Modeling of Failure
The goal of this project is to develop a predictive multi-scale physical model for the Thermo-Mechanical Fatigue (TMF) failure of a cast iron material, which is a typical case of a microstructurally complex material subjected to complex loading conditions. The model will allow unraveling of the critical conditions triggering microstructural damage initiation, propagation, and ultimate failure as a function of microstructural and loading variables.
From Damage to Fracture in Dual-Phase Steels: A Focused Experimental–Numerical Approach
In the automotive industry the trend is to use more and increasingly stronger high-strength steel (HSS) and advanced high-strength steel (AHSS). The main driver for this trend is to improve crash safety without making the car heavier, as fuel consumption and CO2 emissions are directly influenced by the weight of a vehicle. The disadvantage of using materials with higher strength is that the ductility is reduced, resulting in an increased fracture risk. This project develops a methodology to statistically characterize damage-prone microstructural features in multiphase microstructures.
The final aim is to develop models that can correctly predict failure, enabling new and important applications.
