Ribs and Webs

Ribs and webs are useful for reinforcing relatively thin walls and avoiding thick sections. In addition to increasing the strength and rigidity of a thin wall, they improve material flow and limit distortion. Rib thickness should not exceed that of the adjoining wall. Where structural requirements indicate thicker ribs, multiple ribs should be used instead. Figure 5a shows recommended proportions for ribs. Figure 5b shows how ribs may be used as a means to provide coring for mass reduction while maintaining the functional strength of the component.
