Heterogeneous materials in extreme environments: multiscale models of chemo-mechanical processes

Supervisor: Lukasz Figiel (WMG)

Extreme volumetric expansion, high temperature gradients, and/or high-frequency vibrations can compromise structural integrity and safety of modern electronic systems (e.g. batteries) made of heterogeneous materials with highly complex microstructures. The objective of this project is to develop multiscale models that couple mechanics with transport of chemical species to gain physical insight into critical stress locations in heterogeneous material systems under in-service conditions. Microscale models will capture an in-situ response of materials undergoing chemo-mechanical processes. Numerical solutions of those microscale problems will generate surrogate microscale models that will be connected with the macroscale via a data-driven homogenisation approach with uncertainty quantification.
