... in determining the resultant springback, because this affects the conditions of deformation. For example, if a very small amount of stretching is superimposed during bending, springback can be reduced or even eliminated. Under pure bending, springback is proportional to R / t for cylindrical tooling ( Ref 15...

For inherently brittle materials (e.g., glass), the last portion of the fracture on the compression side of the bend may turn sharply at an oblique angle to form a “compression curl.” Torsional loading of cylindrical sections ( Fig. 2d ) results in fracture...
