Fig. 204 Surface of the fracture in Fig. 203 . Note that the radii of the keyway edges have acted as origins for fatigue cracks. A second fatigue zone is visible on the side opposite the keyway. The region between the fatigue zones underwent fast fracture. 2× More

Fig. 26 Incorrect and correct shaft-shoulder heights and fillet radii for mounting rolling-element bearings on shafts. (a), (b), and (c) Incorrect designs. (d) Correct design. See text for discussion. More

Fig. 9 Large magnesium forgings. Corner and fillet radii are given in Tables 14(a) and 14(b) . More

Fig. 21 Minimum fillet and corner radii for steel forgings More

Fig. 22 Recommended fillet and corner radii in relation to height of rib or boss More

Fig. 7 Sections of forgings with different sizes of corner and fillet radii. (a) Conventional forging. (b) Corresponding blocker-type forging. Dimensions given in inches More

Fig. 10 Correlation of height of ribs with radii for (a) corners and (b) fillets of actual aluminum alloy and steel forgings of all principal types. Data are derived from Table 1 and Table 2 More

Fig. 11 Average minimum sizes of radii for (a) corners and (b) fillets with confined webs, as suggested by forging users and forging producers. Data are derived from Table 3 More

Fig. 20 Corner-layout method for wide shells with large corner radii in areas B and C in Fig. 18 More

Fig. 3 Seven typical deep-drawn parts. Corner radii comply with standard commercial practice. Table 2 lists typical die materials used for drawing parts of similar configuration. Dimensions given in inches More

Fig. 26 Correlation of tensile elongations with minimum bend radii ( R ) and thicknesses ( t ). Letters on data points refer to materials listed in Fig. 1 except for S and T, data points for aluminum alloys. More

Fig. 6 Forming tools (left to right): satellite tools with radii of 3, 5, and 15 mm, respectively, and a 15 mm plastic tool. Source: Ref 3 More

Fig. 9 Edge radii design features. Source: Ref 6 More

Fig. 9 Two types of cavities requiring different coring methods. (a) Corner radii must be sacrificed if metal cores are used. (b) Corner radii can be obtained with sand, plaster, or other expendable core material. Casting cost is higher for option (b) due to the additional operations of core More

Fig. 17 Minimum fillet and corner radii for steel forgings More

Fig. 18 Recommended fillet and corner radii in relation to height of rib or boss More

Fig. 6 Corner radii can make an enormous difference in final part performance. Reprinted from Ref 1 with permission by Elsevier. Copyright Elsevier 2017 More

Fig. 16 Adequate length in the snap lock reduces stresses. Full radii at the base of the slots eliminate stress concentrations. Clearance was provided between the snap lock and mating part, enabling the molder to easily remove steel in the mold for a tighter fit, if required. More
