The advent of advanced manufacturing and materials technologies now provides the
capabilities to architect microstructured materials such as 3D printed lattice structures,
fiber-reinforced or multiphase composites, foams, electro- or magneto-active polymers.
The mechanical and multifunctional behaviors of these metamaterials can be tailored to
their specific engineering applications and are often highly nonlinear, anisotropic,
inelastic, and multiphysical. Thus, classical constitutive models are typically not
flexible enough to model their effective material behavior in multiscale and
multiphysics simulations, while concurrent multiscale approaches are inherently
computationally expensive and slow. Thus, in recent years, the formulation of
constitutive models using highly flexible machine learning and surrogate modeling
methods such as artificial neural networks and deep learning, Gaussian processes, radial
basis functions, clustering methods, etc. has gained momentum. Nevertheless, many
challenges remain to be addressed for machine learning-based material models, such as
their accuracy, reliability and physical soundness, their efficiency, the consideration of
parametric dependencies or uncertainties, etc.
This minisymposium welcomes contributions on the state-of-the-art of machine learning
methods for inelastic, multiscale and multiphysics materials modeling. It is intended as
a fruitful moment of interdisciplinary exchange of ideas.
