"[CC01DCAF8256]" . "A computationally attractive procedure is proposed to formulate a Periodic Unit Cell (PUC) for a masonry structure with disordered geometry. Such a unit cell, in order to represent the original structure in a proper sense, results from matching geometrical statistics related to the original structure and the idealized unit cell, respectively. The geometrical input data are obtained from digitized photographs of real historical structures. The parameters of the unit cell then follow from a minimization problem, defined in terms of suitably selected statistical descriptors such as two-point probability functions. The resulting optimization problem is efficiently solved by a global optimization technique based on genetic algorithms. The quality of the periodic unit cell is judged by numerical evaluation of elastic effective properties."@en . "Homogenization of Stone Masonry with Irregular Geometry" .
