Influence of variation of strain rate sensitivity on limit strain of superplasticity

Scripta Metallurgica, 1987
Superplasticity is associated with large tensile elongation and high strain rate sensitivity. This paper analyzes theoretically the influence of variation of high strain rate sensitivity on necking and limit strain. Topics considered include metals, plasticity, strain rate, tensile properties, elongation, and sensitivity analysis.

Plane-Strain Plastic Flow of Strain-Rate Sensitive Materials

Journal of Engineering Materials and Technology, 1974
A numerical method based on the modified Hencky and Geiringer equations is described for solving plane-strain metal flow problems of strain-rate sensitive materials. The slip-line field and flow-stress distributions are determined simultaneously using an iterative calculation.

Strain Hardening and Strain-Rate Sensitivity of an Extruded Magnesium Alloy

Journal of Materials Engineering and Performance, 2008
The strain-hardening behavior and strain-rate sensitivity of an extruded AZ31B magnesium alloy were determined at different strain rates between 10−2 and 10−5 s−1 in relation to the thickness of specimens (2.5 and 4.5 mm). Both the common approach and Lindholm’s approach were used to evaluate the strain-rate sensitivity. The yield strength (YS) and the

Influence of Strain Rate, Temperature, Plastic Strain, and Microstructure on the Strain Rate Sensitivity of Automotive Sheet Steels

steel research international, 2012
AbstractThis work identifies the influence of strain rate, temperature, plastic strain, and microstructure on the strain rate sensitivity of automotive sheet steel grades in crash conditions. The strain rate sensitivity m has been determined by means of dynamic tensile tests in the strain rate range 10−3–200 s−1 and in the temperature range 233–373 K ...

Materials Sensitive to Slow Rates of Straining

1970
In precrack Charpy slow-bend and impact tests of D6aC high-strength steel at 300 to 500 F, there was a reduction in slow-bend fracture energy as the test temperature was increased; whereas, there was an increase in impact fracture energy over the same temperature range.

Strain rate sensitivity of a high strain rate superplastic TiNp/2014 Al composite

Journal of Materials Processing Technology, 2010
Abstract The effects of deformation temperature and strain in hot rolling deformation on strain rate sensitivity of the TiN p /2014 Al composite were studied by tensile tests conducted out at 773, 798, 818 and 838 K with the strain rates from 1.7 ×10 −3 to 1.7 × 10 0  s −1 .

The Effect of a Lathyritic Diet on the Sensitivity of Tendon to Strain Rate

Journal of Biomechanical Engineering, 1985
While the tensile failure properties of rat-tail tendon depend on strain rate, the sensitivity to strain rate decreases with age, especially during sexual maturation. The object of this study was to determine the effect of an experimental model of chronic lathyrism on age-dependent changes in the sensitivity of developing tendon strength to strain rate.

Influence of strain aging on the strain-rate sensitivity of the flow stress

Scripta Metallurgica, 1982
Previously published studies on the deformation kinetics of several fcc alloys, i.e. single crystals of Al-0.7% Mg, polycrystals of AlMg, Inconel 600, Inconel X750, NiCo, AuCu, and FeC, are cited, and two models are proposed to explain the reported observations. The calculations suggest that excess vacancies play an important role in the dynamic strain
