Abstract: | We develop a method for determining power-type complex singularities of solutions for a class of one-dimensional singular
integral equations with generalized kernels and complex conjugate unknown functions. By analyzing the characteristic part
of a singular integral equation, we reduce the problem of determining the solution singularity exponents at the ends of the
integration interval to two independent transcendental equations for these exponents. We show that the distribution of admissible
singularity exponents is of continuous character. We present numerical results for a two-dimensional elasticity problem whose
mathematical statement leads to a singular integral equation of the class under study. We also reveal the drawbacks of one
classical approach to the determination of stress field singularities. |
