Modeling of fracture in high-strength steel based on phenomena at the nano-and micro level.
The project aims at predicting fracture properties and their statistical distribution based on the distribution of precipitates/inclusions in the steel. Microstructural variation, in particular precipitates and inclusions, will be studied and modelled. This will give the statistical distribution of them. This information will be used to generate finite element models (Statistical Volume Ensembles) used to study the deformation of the generated microstructure up to fracture. The fracture properties have the largest sensitivity with respect to variations in microstructure. The results from the simulations will be used to calibrate macroscopic constitutive models, including their statistical distribution. The work is done in cooperation with researchers at Northwestern University. They are led by Prof W.K. Liu, world leading researcher in the field of computational mechanics.
