A new model of thin elastic rectilinear inclusion has been constructed. An approach to the stress-strain state analysis in an isotropic plane reinforced by a periodic system of thin elastic inclusions has been suggested. The formulae for determination of the effective modulus of composite material and stress intensity factors at the inclusion tip depending on volumetric contents of the reinforcing elements and their elastic characteristic have been obtained. Numerical analysis of the problem for various geometrical and mechanical parameters of the composite has been presented. The effect of the ratio between inclusion and matrix elastic modul on the values of stress intensity factors has been studied as well.

W pracy przedstawiono metodę modelowania stanu naprężeń i odkształceń w ciele izotropowym wzmocnionym periodycznym układem cienkich sprężystych inkluzji. Otrzymano równania określające moduły efektywne kompozytu oraz współczynniki intensywności naprężeń w wierzchołkach inkluzji. Przeprowadzono analizę współczynników intensywności naprężeń w zależności od efektywnych modułów.
