REDUCING PERIODICITY IN MICROSTRUCTURE RECONSTRUCTION OF HETEROGENEOUS MATERIALS
Doškář M., Novák J.
pages 152 - 155, full text

An approach to modelling of heterogeneous materials by means of Wang tilings is outlined in the paper. The presented tiling concept can be understood as an extension to the widely accepted Periodic Unit Cell (PUC) approach. Unlike in the case of PUC, the microstructural information is compressed within a set of Wang tiles instead of a single cell, which allows us to eliminate periodicity and efficiently control long range orientation orders of a microstructure reconstruction. In this contribution tile morphology design based on the automatic tile design is used. Further enhancement reducing the repetitiveness by microstructural patch is proposed. A sensitivity study of automatic design parameters is performed in order to preserve spatial features of original microstructure.
