Reconstruction of Random Media via Multi-Objective Optimization
A. Pospíšilová, M. Lepš
pages 240 - 241, full text

To simplify numerical analyzes of complicated real microstructures, a material representation in terms of Representative Volume Element (RVE) has been introduced. It is based on a binary (black and white) image, which statistically resembles the corresponding real microstructure. To characterize microstructure and assess the proximity of the compressed representation to the reference microstructure, several statistical descriptors are usually employed. In one of the approaches to construction of RVE, a unit cell is derived from the optimization procedure formulated in terms of selected statistical descriptors. The aim of our work is to resolve this issue by multi-objective optimization techniques. The goal is to approximate as closely as possible the true Pareto front as a trade-off of competing objectives.
