Abstract

In the work the spatial problem of elastic tenses concentration calculation around circular cracks placed in one plane was examined. An approximate formula for tense intensity coefficient calculation around these cracks was received. The problem is formulated as integro-differential equation. To solve it, orthogonal polynomials method and small parameter method were used. The dependence of tense intensity coefficient from distance between cracks and their radiuses was examined.
