Project Description
Advanced manufacturing processes with granular materials (e.g., sintering or powder compaction) often involve high potential electric fields, dynamic loading, and large strains. As such, our fundamental knowledge needs to expand towards understanding the complex multiphysics involved to best optimize these processes. This will be achieved with an integration of novel capabilities integrated with synchrotron X-rays to examine the complex multi-particle interactions of large granular systems in operando. Results will also potentially help further validate large multi-particle computational simulations to improve models. The success of the project will eventually lead towards a workflow for guided materials design.
