    Statystyczna charakteryzacja miar geometrycznych mikrostruktur losowych: definicje, właściwości i zastosowania
    (Wydawnictwa AGH, 2009) Łydżba, Dariusz; Różański, Adrian
    The paper deals with statistical analysis of random two-phase heterogeneous media. The n-point probability and the lineal-path functions are considered. Both correlation functions are calculated using algorithm based on Monte Carlo simulations. Three different types of random microstructures are studied. Basing on numerical results, some properties of these correlation functions are presented as well as an example of their application.

    Wielkość próbki a reprezentatywność geometryczna mikrostruktury kompozytów losowych
    (Wydawnictwa AGH, 2010) Łydżba, Dariusz; Różański, Adrian
    The paper analyses geometrical representativity of samples randomly chosen from statistically homogeneous two-component composite. Quality of 2-point probability function replica is used as a measure of geometrical representativity of the sample. It is pointed out that there exists a minimal sample size beyond which a satisfactory replica of 2-point probability function could not be obtained. The condition for minimal sample size is formulated in the paper. Numerical simulation conducted for three different kinds of microstructure confirm effectiveness of the condition proposed.
