Limit strains in the sheet forming of strain and strain-rate sensitive materials
Journal of Mechanical Working Technology, 1985Abstract Forming-limit diagrams are a convenient way of displaying the limits of performance of a sheet material in pressing and stamping: they represent the limiting combination of strains after which unacceptable necks are formed in the material.

Mechanism of negative strain rate sensitivity in metallic glass film
Journal of Alloys and Compounds, 2019The observation of negative strain rate sensitivity during nanoindentation is a common, yet poorly understood phenomenon in metallic glasses. In this study, a combination of experimental investigation and atomistic simulation has been employed to ...

Strain-rate sensitivity of the rabbit MCL diminishes at traumatic loading rates
Journal of Biomechanics, 2002This study was performed to determine whether the viscoelastic behavior of ligaments persists at high rates of loading, such as those associated with sports-related trauma or motor vehicle accidents. Medial collateral ligaments (MCLs) from 22 skeletally mature New Zealand White rabbits were tensile tested quasi-statically and via two impact conditions ...

Material Strain Rate Sensitivity
2001The 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 (\(\dot \varepsilon \)).

Remarkable strain-rate sensitivity of nanotwinned CoCrFeNi alloys
Applied Physics Letters, 2019Strain-rate sensitivity (SRS), which affects the mechanical properties of materials at high strain-rates and their service life, is an important indicator for nanostructured materials.

The strain-rate sensitivity of α-uranium
Journal of the Mechanics and Physics of Solids, 1959Abstract 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 ...

Strain-rate sensitivity of zinc sheet
Metallurgical Transactions A, 1984The 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.
