![]() The corresponding generation methods are classified into three categories: (i) experimental methods targeting reconstruction through experimental characterization of the microstructure, (ii) physics based methods targeting simulation of the physical process(es) responsible for the microstructure formation and evolution, and (iii) geometrical methods concentrating solely on mimicking the morphology (ignoring the physical basis of the microstructure formation process). Further subdivisions are realized based on various morphological features. Here, we divide heterogeneous solids into porous and non-porous media, with 0 < void volume fraction < 1 and void volume fraction = 0, respectively. ![]() ![]() To this end, we present a systematic classification considering a wide range of heterogeneous materials of engineering interest. This work reviews state of the art representative volume element (RVE) generation techniques for heterogeneous materials.
