Using the Kelvin-Somigliana formulae, the problem of two coplanar square cracks in a three-dimensional infinite isotropic elastic body is reduced to solving three two-dimensional singular boundary integral equations. The numerical method of quadratic elements is proposed for the above- mentioned equations. The stress intensity factors of mode I, mode II and mode III are numerically calculated for a few examples.
