Strain-rate sensitivity of zinc sheet

Metallurgical Transactions A, 1984
The flow stress of many commercial alloys depends on applied strain rate, and this dependence contributes to their resistance to strain localization (necking). Measurement of strain-rate sensitivity for these alloys is complicated by possible dependence on strain, strain rate, testing method, and method of analysis.

Strain-Rate-Sensitive Constitutive Law for Concrete

Journal of Engineering Mechanics, 1999
Concrete strength is highly sensitive to loading procedure, especially in the range of high strain rates. On the basis of experimental results, it is demonstrated that the full loading history must be included in a dynamic constitutive model, not just consideration of the current strain rate.

Material Strain Rate Sensitivity

2001
The theoretical analyses developed in chapter 1 have examined the influence of inertia on the response of an elementary structure subjected to dynamic loads which cause plastic behaviour. The yield criterion, which governs the plastic flow, was assumed to be independent of the rate of strain (\(\dot \varepsilon \)).

Impulsively Loaded Strain-Rate-Sensitive Plates

Journal of Applied Mechanics, 1967
The response of an impulsively loaded, isotropically rate-sensitive annular plate is calculated via “exact” and approximate viewpoints. For a typical example, numerical results differed by about 3 percent. The essence of the approximate approach, which represents a natural extension of a previous one-dimensional analysis [1], is that the initial stress

Operant strain-rate sensitivity during tensile necking

Metallurgical Transactions A, 1983
Precisely machined tensile specimens of aluminum-killed steel sheet were used to measure the continuous strain-rate sensitivity,m c, in a series of isothermal tests at different crosshead speeds.m cwas found to be independent of strain and strain rate, in contrast with the “jump” test instantaneous strain

Strain rate sensitivity of skin tissue under thermomechanical loading

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
There have been limited studies addressing the thermally dependent mechanical properties of skin tissue, although this can contribute to a variety of medical applications. To address this, an experimental study on the tensile behaviour of pig skin tissue under different thermal loading conditions and different mechanical stretching rates ...

The strain-rate sensitivity of α-uranium

Journal of the Mechanics and Physics of Solids, 1959
Abstract Experiments are described in which specimens from two different batches of uranium were subjected to both static and dynamic compression tests. From such tests static and dynamic stress-strain curves were obtained. These stress-strain curves indicate that α-uranium is slightly strain-rate sensitive; for instance, the effect of increasing ...

Study on Strain-Rate Sensitivity of Cementitious Composites

Journal of Engineering Mechanics, 2010
In this study, we conduct a combined experimental and micromechanical investigation into the strain-rate sensitivity of concretes, with a special reference to the effect of aggregate concentration. We first measured the stress-strain relations of Type I portland cement with 0.45 water-to-cement ratio (w/c), and then those of the mortar containing sand ...

Strain rate sensitivity of ultra-low carbon steels

Materials Science and Engineering: A, 2001
Abstract Ultra-low carbon, interstitial free (IF) steels were prepared by an intermediate rolling reduction of 20% followed by a 3 or 9 day anneal at 400°C prior to further reduction and anneal. Previously described determination of the interstitial content using the Haasen plot intercept indicates that levels in the ppb range were attained.
