Web7 Oct 2024 · The spherical indentation test has been successfully applied to inversely derive the tensile properties of small regions in a non-destructive way. Current inverse methods mainly rely on extensive iterative calculations, which yield a considerable computational costs. In this paper, a database method is proposed to determine tensile flow properties … Web17 Aug 2024 · In tensile testing, if the specimen has yielded, i.e. section ‘bc’ in the diagram above, the specimen continues to elongate even though the load no longer increases, and thus a horizontal interval appears in the tensile curve, a phenomenon known as yielding or flow. The yielding phenomenon is caused by the slippage of crystals in the metal. WebOver the years, several flow relationships have been proposed [5-11] to describe the tensile flow and strain-hardening behavior in metals. Constitutive models are explained at the microscopic level and the macroscopic level.
