7c, larger negative bending moment is generated and it implies that the magnitude of compressive stress near the film side surface is larger than that shown in Fig.
It is concluded that the bending moment of the FIM part decreases as the mold temperature difference increases because the negative bending moment becomes larger with the increasing deflection against the normal direction of the film surface.
One of the criteria for fixing the cable prestressing force is aimed at the reduction of max positive and negative bending moments (the presented method with some modifications is valid also for other purposes: controlling the permissible tensile and compressive stresses, etc.
