RÉSUMÉ

A numerical analysis of the fields of structural stresses and strains in unidirectional fibrous composites of quasi-periodic structure on accidental technological deviations of the positions and orientations of the structural elements of a material in the transversal plane is carried out. Algorithms for computer synthesis of quasi-periodic structures have been developed with allowance for the given laws governing the distribution of the geometric parameters of the material’s elements. The statistical dependences of the fields of structural stresses and strains on the magnitude of deviations of the geometric characteristics of inclusions have been analyzed and estimation of the possibility of microdestruction of structures made from these materials has been performed.
