Question details

Blanking on a brass alloy plate 85-15 (CR) (K = 580 MPa, n = 0.34) thickness s = 2 mm and width B = 40 mm.

(a) Calculate the shear force required to cut its surface following form (based on the types of Notes)

(b) What changes to the above calculation if the relationship is used: Pmax = 0.7 x (UTS) x (s) x (L)

(c) You proposed a technically correct arrangement of the incised pieces on the plate and
calculate the exploitation coefficient.
