In this paper, ‘The body force doublet method’ is proposed. This method of analysis uses the distributed body force doublet in order to satisfy given boundary conditions. For application, single-edge-cracked specimens under three-or four-point bending are analyzed, and the stress intensity factors and the crack opening displacements are evaluated. Their approximate expressions, effective for practical application, are shown.
