The thickness of a cold-rolled sheet varies from 0.0322 in. to 0.0318 in., depending on where the measurement is made, so strip tensile specimens cut from the sheet show similar variation in cross- section. A. For a material with n = 0.20 and m = 0, what will be the thickness of the thickest regions when the thinnest region necks? B. Find the strains in the thicker region if m=0.50 and n=0 when the strain in the thinnest region reaches i. 0.5, ii.co The thickness of a cold-rolled sheet varies from 0.0322 in. to 0.0318 in., depending on where the measurement is made, so strip tensile specimens cut from the sheet show similar variation in cross- section.
