Material Twin for composite material microstructure generation and reconstruction

Abstract

The paper describes the modelling and the subsequent implementation of an integrated system that consists of a composite material microstructure and its Material Twin (MT). The developed MT is based on statistical continuum theory and probability functions. The MT is used to reproduce/reconstruct 3D porous composite material microstructures, to simulate the multi-physical behaviour of this composite material system and to design desired anisotropic 3D microstructures. To correlate the effective physical properties of a composite material system to its microstructure, we use probability functions in conjunction with the strong-contrast formulation. A practical use case dealing with porous materials demonstrates the versatile advantages of the implemented approach with respect to its prediction and design capabilities.
