Full Project Detail Metal alloys used in automotive and aerospace industry are subjected to extreme loading and environmental conditions. Large strains developed during manufacturing or under operational conditions often lead to localisations and fractures across different scales. Hence, the accurate description and modelling of the mechanical performance in these settings is a challenge for the understanding of materials’ failure and the design of structural components that operate under extreme conditions.
The proposed research project aims at the systematic observation, quantification, and prediction of localised deformation modes triggered by the microstructure, in a class of lightweight metal alloys. The project workplan offers a unique opportunity for skills development as it comprises experimentation and advanced numerical simulations. Specifically, state-of-the art monitoring techniques (SEM, HR-DIC) will be used to quantify specific microstructural features that drive deformation at the microscale. In parallel, numerical codes at the crystalline level capable of predicting localisation and fracture (peridynamics, XFEM) will be developed and validated against the obtained experimental datasets. These tools are expected to have real world impact and affect the future design of such engineering alloys.
