Abstract: The exact complex stress functions are obtained for a infinite plate with a centrical crack or semi-infinite crack under concentrated forces at a certain point. The analytical method is Cauchy integration for a infinite plate with semi-infinite crack. The problem for a infinite plate with centrical crack is reduced to the Hilbert problem.

Key words: complex stress function, Cauchy integration, Hilbert problem
