A NOTE ON THE EFFECT OF BENDING STIFFNESS OF STRINGERS ATTACHED TO A PLATE WITH A CRACK

摘要

An infinite stringer which is assumed to be partially bonded to a plate through a layer of adhesive is considered. The stringer is assumed to have bending as well as longitudinal stiffness. The effect of the stringer's bending rigidity on the stress intensity factor at the tip of the crack is illustrated. Shear stress dies attribution between the plate and the stringer and the stress intensity factors will be obtained from the solution of a system of Frsdholm integral equations which represent the continuity of displacements along the line of bond.
