摘要
This short paper will present a two-dimensional (2D) model of concrete material, based on probabilistic models: it is a combination of a Voronoi tessellation for the gravel, followed by a Boolean model of spherical grains for the air-voids, with elimination of the air-voids-gravel intersections so that there is no contact between them. The model was tested via crossed-covariance. Results on true and simulated structures are in good agreement. This is a first step towards a 30 model. (C) 2001 Elsevier Science Ltd.
