What Happens After Ultimate Tensile Strength?

What Happens After Ultimate Tensile Strength? However, once the tensile strength is exceeded, the test specimen begins to thin down, or neck, at some location along the length. All of the rest of the deformation to failure occurs at this point as the stress is concentrated in this area of reduced cross section. Does necking

What Is Necking In Tensile Test? Necking occurs when an instability in the material causes its cross-section to decrease by a greater proportion than the strain hardens when undergoing tensile deformation. … Necking behavior is disregarded in calculating engineering stress but is taken into account in determining true stress. What is necking on a graph?
