The stress state of the semi-strip with a transverse crack is investigated. The mechanical load is
applied to the semi-strip’s short edge. The initial problem is reduced to the one-dimensional vector boundaryvalue problem with the help of the semi-infinite Fourier transformation applied by the generalized scheme. The vector boundary-value problem is solved with the help of the matrix differential calculation apparatus and Green’s matrix-function apparatus. The solving of the problem is reduced to the solving of the system of three singular integral equations (SSIE). First singular equation contains two fixed singularities, so the special method is used for the SSIE’s solving. Stresss intensity factors (SIF) are calculated for the different crack’s length
