Stochastic numerical model of stone-based materials with realistic stone-inclusion features

This paper presents a systematic approach for generating a stochastic model with realistic stone-inclusion features for the numerical simulation of stone-based materials. Firstly, the inverse discrete Fourier transform method is employed to randomly generate realistic stones with predetermined particle shape features. Then, an overlapping detection algorithm is proposed to facilitate random and quick allocation of irregularly shaped stones, considering the stone contents, stone size distributions and stone orientations. Finally, several examples are provided to show that the proposed approach can generate stone-based materials with prescribed stone features in a rapid and precise manner. (C) 2018 Elsevier Ltd.
