Abstract
The problem of determining the dynamic stress intensity coefficients for two cracks emerging from a single point is solved. The cracks are affected by a longitudinal shear wave. The original problem is reduced to solving a system of two singular integro-differential equations with fixed singularities. For an approximate solution of this system, a numerical method is proposed that takes into account the real asymptotics of the unknown functions and uses special quadrature formulas for singular integrals.
