Abstract:
Numeral solutions of tasks of I–II types stationary cracks when mixed boundary conditions are set on their borders, are presented in this article. The tasks solution is fulfilled with method of disconnected biases. Normal and shearing openings of cracks length where normal and shearing stresses are set are approximated with functional dependences. Stress intensity factors of the first and second types $K_{I}$, $K_{II}$ for cracks, on borders of which mixed boundary conditions are set, are determined by using the criteria based on disconnected biases.
Keywords:
crack, mixed boundary conditions, stress intensity factors of I and II types.
