abstract = {This paper proposes the use of adaptive polynomial chaos expansion (PCE) for uncertainty propagation analysis of
the numerical homogenisation of polymer composites doped with random dispersions of spherical inclusions. The
developed PCE acts as a surrogate model bypassing the computationally intense numerical homogenisation of the
elastic properties of 2D/3D representative volume elements (RVEs) loaded with moderate to high filler contents.
Numerical results and discussion are presented to assess the accuracy and computational efficiency of 2D and
3D homogenization meta-models. The ability of the developed approaches to perform uncertainty propagation
analyses with minimum computational effort represents the main contribution of this work, which holds vast
potential for the stochastic design of macroscopic composite structural elements.},
