... on the bend radius, bending angle, and the sheet thickness. Three-point bending tests were conducted to determine the bendability of the AHSS in comparison with high-strength steel ( Fig. 6.12 ). The bendability is defined as the minimum r / t ratio, where r is the minimum bending radius at the bending...

...). Perhaps, the conclusive factor may be the force supplied by the moderate “bendability” and “restoring force” of the pole ( Fig. 1.9b ). Glass will become remarkably stronger when it is drawn at a temperature over the softening point (approximately 1100 K) ( Fig. 1.9c ). Glass fiber reinforced plastic...

.... Note that bendability improves with the smaller r/t value: For the same thickness, a smaller minimum radius means a tighter bend is required. Figure 10.8(a) shows an example of sheet bending and the calculation of r/t. An r/t value of 0 means a flat 180-degree bend can be made without cracking...

... guidelines for the minimum bending radii of AZ31-O/H24 alloy sheets (thickness: 0.51 to 6.3 mm, or 0.02 to 0.249 in.). These minimum bend radii are based on bending a 152 mm (6 in.) wide specimen through 90°. It is clearly seen that bendability of an annealed (-O) magnesium alloy is higher (5.5 t 0 ) than...

The average plastic anisotropy is a good measure of the drawability of a material but has very little effect on its stretchability or bendability. Beside geometric anisotropy, hardening anisotropy is also important in sheet metal forming...
