Abstract: The mutual influence of round and elliptical cracks in three-dimensional space is investigated. The stress intensity factors for various problems are calculated. The dependence of the stress intensity factors on the ratio of the semiaxes of the ellipse is investigated. The computational error does not exceed 1%.
Key words: three-dimensional space, elastic medium, crack, stress intensity factor, boundary element method, discontinuous displacement method.
