Plastic state of metal
Webb21 dec. 2024 · Superplasticity is the ability of metals to exhibit extremely large elongations of at least 300% prior to tensile failure, when deformation is imposed at relatively low strain rates (e.g., ε ˙ = 10 −3 to 10 −5 s−1) and elevated temperatures ( T > 0.5 Tm ), where Tm is the melting temperature of metals ( Edington, 1982; Langdon, 1982 ). WebbTools. Plastic deformation of a thin metal sheet. Flow plasticity is a solid mechanics theory that is used to describe the plastic behavior of materials. [1] Flow plasticity theories are characterized by the assumption that a flow rule exists that can be used to determine the amount of plastic deformation in the material.

Reviewed in the United States 🇺🇸 on April 10, 2024 Typical flow plasticity theories for unidirectional loading (for small deformation perfect plasticity or hardening plasticity) are developed on the basis of the following requirements: 1. The material has a linear elastic range. 2. The material has an elastic limit defined as the stress at which plastic deformation first takes place, i.e., .
