Contribution

It presents a novel statistical approach that uses micrograph-based simulations to analyze damage site environments in multi-phase materials.

Findings

Identified typical microstructural features around damage sites

Demonstrated the feasibility of micrograph-based statistical simulations

Abstract

Understanding the microstructural influence on the failure mechanisms in multi-phase materials calls for the identification of the worst-case scenario. This necessitates a statistical approach. By performing simulations directly based on micrographs, such an approach becomes feasible. This is applied here to extract the average microstructure around damage sites.
