✦ Synopsis

Using the Somigliana formula and concepts of the finite-part integral, a set of hypersingular integral equations to solve the arbitrary flat crack in three-dimensional elasticity is derived, then its numerical method is proposed by combining the finite-part integral method with the boundary element method. In order to verify the method, several numerical examples are carried out. The results of the displacement discontinuities of the crack surface and the stress intensity factors at the crack front are in good agreement with the theoretical solutions.

## Abstract The β€œconventional” finite element‐boundary integral (FE‐BI) method suffers from two major drawbacks, one is the huge computer resources required by the dense BI submatrix; the other is the slow convergence rate of the resulting linear system of equations.

Using the single crack solutions and the regular solution of harmonic function, the bending problem of a cracked cylinder is reduced to solving two sets of mixed-type integral equations which can be solved by combining the numerical method of the singular integral equation with the boundary element
