1.	Necking is a localized elongation through which the load carrying capacity of material increases beyond its tensile strength.(a) True(b) FalseThis question was addressed to me in an international level competition.I would like to ask this question from Relationship between Tensile and Shear Yield Stress in chapter Types of Die & Metal Forming Processes of Casting-Forming-Welding II
Answer» Right choice is (b) False For explanation: In the stress-strain CURVE, beyond the tensile strength, the LOAD carrying capacity reduces and the test material goes through a localized elongation called NECKING. There is no any CONSTANT strain in this region and the elongation occurs in one small segment of specimen. The stress measured just before the FAILURE is known as the fracture stress.
