The stress intensity factors of rectangular plates with a single-edge crack or double-edge cracks under transverse bending are evaluated by the body-force doublet method. The stress field due to a pair of point moments (doublet) in a semi-infinite plate is used to solve these problems. According to the results, the effect of plate length on K₁ is less under transverse bending than under uniform tension, in rectangular plates of the same form.
