摘要：

Improved characterization of present-day materials that are manufactured to obtain optimal property values by microstructure effects necessitates a more thorough knowledge of the microstructure pattern. Methods of spatial statistics have been used to analyse patterns of second-phase inclusions as observed on planar sections. Several parameters and functions that discriminate between different dispersions of inclusions have been investigated. The effects of inclusion patterns on the interface stresses in unidirectional fibre reinforced composite material are discussed. The range of a local geometrical disorder and a physical range of interaction between stresses and positions of inclusions are obtained for investigated patterns.
