The strain associated with this uniform elongation is calleduniform strain Note that the uniform strain will have both elasticand plastic components After the tensile strength has beenreached the specimen will undergo nonuniform strain Most of theremainder of the deformation will be highly localized in aphenomenon known as neckingDuring nonuniform deformation the minimum crosssectional areadecreases as the test proceeds so the    See Answer
