Abstract Since Reissner and Mindlin proposed their classical thick plate theories, many authors have presented refined theories including transverse shear deformation. Most of those plate theories have tended to use higher order power series for displacements and stresses along the thickness in order to achieve the higher accuracy. However, they have not carefully noticed lateral load effect. In this paper, we pay attention to constitution of the lateral loads: a body force and upper and lower surface tractions. Especially we formulate a modified theory for plate bending, in which the effect of a body force is distinguished from that of surface tractions. The present plate theory includes not only transverse shear deformation but also transverse normal stress effect. In this paper, our attention is focused on bending moment behavior of plates.
