Symposium description
There is a growing demand for the modelling, simulation and validation of materials that can respond to multiple stimuli (i.e. thermal-, electro-, magneto-, chemo-) in potentially extreme environments (i.e. high temperature, corrosive). This session aims to gather scientists working across a variety of material systems to share recent advances in the modelling and simulation of coupled problems in the mechanics of materials. The session seeks to bring together both experimental and numerical techniques across multiple length scales. Topics of interest include, but are not limited to:
Materials and processes
- Materials for energy storage, harvesting and/or conversion, including batteries, flexible energy harvesters, etc.
- Soft active materials, including dielectric elastomers, magneto-rheological elastomers, liquid crystal elastomers, hydrogels, etc.
- Thermo-chemo-mechanical couplings, including mechano-transduction, chemical reactions, coupled mass transport and deformations, electrophysiology, etc.
- Material degradation driven by a coupled process, including oxidation, hydrolysis, corrosion, hydrogen embrittlement, etc.
- Electro-, magneto- mechanical couplings, including piezoelectricity, ferroelectricity, pyroelectricity, ferromagnetism, etc.
- Electro-magneto-acousto interactions, such as in the context of MRI scanners or fusion reactors
- Modelling of growth, especially when induced by a coupled physical phenomenon
- Experimental protocols and approaches that support model development
Computational techniques
- Advanced continuum mechanics formulations
- Sophisticated thermo-dynamically consistent constitutive models
- Scale bridging and homogenisation strategies, including rank laminates, FEM2, mean field or asymptotic homogenisation, etc.
- Phase field methods for muti-physics problems
- Computational mesh based methods (Finite Element, Finite Volume, Discontinuous Galerkin, etc.) and meshless methods (Peridynamics, Smooth Particle Hydrodynamics, etc.) for multi-field coupled problems
- Alternative Machine Learning approaches for coupled problems
- Material stability, polyconvexity, geometrical instabilities, bifurcation analysis
