Nanocomposites Modelling Group

Mission

The Nanocomposites Modelling Group (NMG) in the IINM is led by Dr. Figiel, and it is focused on the development of multiscale modelling tools to optimise the multi-physics performance of advanced engineering materials and components with micro- and nano-size inclusions, using the theories of thermodynamics, continuum mechanics, homogenisation, linked with numerical implementation using the finite element method and machine learning approaches.

The Group works closely with the Warwick Centre for Predictive Modelling (WCPM), and the Centre for Scientific Computing (CSC) at the University of Warwick on a range of research projects focussing on the development of robust methods for quantification of uncertainties in multiscale materials models, data-driven multiscale approaches and development/application of efficient high peformance computing for those models.

Research themes

I. Multiscale modelling of chemo-mechanical problems

This theme is focussed on the development of a multiscale chemo-mechanical modelling framework in the finite-strain setting, to predict the multi-physics response of advanced heterogeneous materials for energy storage (e.g. Li-ion batteries, solid-state batteries) - below, examples of completed research:

II. Multiscale modelling of electro-mechanical problems

This work aims at developing coupled multiscale models using relevant scale-transitions to predict multi-physics response (e.g. piezoelectric, dielectric) of complex polymer-based composite systems.

III. Multiscale Prediction of Processing of Polymer Composites

Processing near the glass transition offers means for enhancing morphology and end-use properties of nanocomposites. This work aims at developing advanced modelling approaches and tools, which capture nonlinear viscoelastic behaviour of nanoparticle-based materials during processing, and enable optimisation of processing parameters.
