1.	Which of the following can help in determining the behaviour of the material in metal forming?(a) Size of material(b) Shape of material(c) Stress-strain curve(d) Color of materialThe question was posed to me during an online exam.My query is from Behaviour in Metal Forming in division Forming Process of Casting-Forming-Welding II
Answer» Right choice is (c) Stress-strain curve The best I can explain: The behaviour of MATERIALS during metal forming can be determined by the stress-strain curve. The stress-strain curve for most of the materials is divided into an elastic region and a plastic region. In metal forming, the plastic region is the MAIN consideration because the MATERIAL is plastically DEFORMED during the forming process.
