Based on the interrelated mathematics knowledge, through an example, the curves forms of composite bending moment diagrams are analyzed in this paper. The discussion is centered on whether the curves' form is concave . It is proved that the curves of composite bending moment diagrams must be concave curves under bending and bending deformation for round shaft.
