Strain Hardening and ‘Strain-Rate Hardening’
1982The limitations of power-law strain hardening and ‘strain-rate hardening’ descriptions are reviewed. It is found that significant advantages can be gained by using, instead, the Voce relation, especially in the proposed modification that accounts for the rate sensitivities of flow stress and of strain hardening.

Strain hardening in liquid-particle suspensions
Physical Review E, 2005The behavior of a liquid-particle suspension induced to sheared motion was analyzed by numerical simulations. When the velocity (strain) of the suspension began to increase, its viscosity first stayed almost constant, but increased then rapidly to a clearly higher level.

Journal of Mechanical Engineering Science, 1972
Continuous and interrupted room temperature compression tests were carried out on geometrically similar specimens of duralumin, pure copper and lead, using steel and ebonite dies. Significant differences in strain-hardening rate were ascribed to heat-transfer during deformation.

On Strain-Hardened Circular Cylindrical Shells
Journal of Applied Mechanics, 1960A consistent kinematic hardening theory termed complete hardening, based on a Tresca initial yield condition, has been applied to determine the general flow laws for rotationally symmetric shells. Representative “long” and “short” cylindrical shell problems with zero axial load are solved using complete hardening and a simpler but approximate kinematic

Dislocation Multipoles and Their Role in Strain-Hardening
Journal of Applied Physics, 1964The stress fields of edge dislocation dipoles are able to trap other edge dislocations that pass nearby. The configurations, energies, and trapping stresses of the resulting tripoles are discussed here in some detail. Dipoles may also interact dynamically with approaching dislocations because they cause fluctuating stresses. The decrease in the average

Strain Hardening and Tensile Properties
The desire for stronger steels probably goes back to the origins of the first transformations of a mixture of ore and charcoal into iron. This was done by the Chalybes and the Hittites in the South Caucasus. The Hittites were certainly the first to use iron in weaponry, as Hittite cuneiform tablets from the 18th-century BCE indicate the production of ...Gouné, Mohamed, Bouaziz, O.

Strain hardening of thermoplastics
Macromolecules, 1993Published stress-strain curves of different thermoplastics in tension are used to evaluate a theoretical equation derived from a model in which the strain hardening effect is related to the Gaussian network theory of rubber ...

STRAIN HARDENING OF DOUGH AS A REQUIREMENT FOR GAS RETENTION
Journal of Texture Studies, 1992ABSTRACTMechanisms that can be responsible for the ability of wheat flour doughs to retain gas are discussed. It is concluded that the relevant types of physical instabilities are Ostwald ripening (disproportionation) and coalescence of gas cells. The extent of Ostwald ripening is probably primarily controlled by surface rheological properties; it ...

Metal Science and Heat Treatment, 1986
1. The nature of the depedence of maximal uniform strain ep and of the strain-hardening coefficient n on the degree of strain hardening and on the heat-treatment regimes is analogous. 2. Strain ep can be calculated by the formula ep=(n −2)/(n −1), where n is determined from the results of two indentations of a spherical indentor.

Strength of Materials, 1981
1. Mathematical treatment of experimental data on establishing relationships between σs and ɛ with the use of the “Nairi” computer confirmed the usefulness of the equation σs = mɛn for describing experimental hardening curves and indicates the very close relationship between σs and; the correlation coefficient is 0.935–0.993, However, for many of ...
