Abstract

Using the approach described in [1], the non-axisymmetric problem of the stress concentration in an unbounded elastic medium near a spherical slit is reduced to three, one-dimensional, separately solvable, integral equations. Their exact solution is obtained in a class of functions with non-integrable singularities and is used, as in [1], to derive simple formulae for the stress intensity factors. The axisymmetric modification of this problem has been investigated in [2–5].
