i) An automotive pressing fails in production. The part is formed by almost pure stretching, using drawbeads in the dies. (a) What would you analyze the problem? (b) What is the likely strain state at the point of fracture (use forming limit diagram). (c) Indicate in the FLD two possible remedies, keeping the shape of the pressing unchanged. (d) If none of this works, what else could be attempted? ii) What sheet' properties would you specify for (a) bending without orange peel; (b) bending to zero radius; (c) greatest resistance to permanent deformation in servico. Justify the choices
