Strain Rate and Strain Rate History Effects in Two Mild Steels.

1979
Abstract : Results are presented of a series of experiments performed with two steels to investigate the dependence of flow stress on strain rate and its history. For this purpose quasi-static, dynamic and incremental strain rate tests were conducted on SAE 1020 hot-rolled steel and SAE 1018 cold-rolled steel at room temperature. It is shown that while

Strain Rate Sensitivity of Flow Stress at Very High Rates of Strain

1996
In order to clarify the mechanism of the steep rise in the flow stress, widely seen in metallic materials at strain rates above about 5×103/sec, two strain rate change tests were conducted. The strain rate reduction test was made for polycrystalline aluminium, copper, iron and niobium at strain rates up to about 2×104/sec.

Strain Hardening and ‘Strain-Rate Hardening’

1982
The 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 Rate Effects

1999
The mechanical properties of most materials vary with the rate of loading and this effect is particularly evident in polymers. It is usual when considering rate of loading effects in a material, rather than a structure, to quantify the loading rate in terms of a strain rate where the strain rate can conveniently be visualised as the number of times a ...

Strain Rate History Effects and Dislocation Substructure at High Strain Rates

1983
A brief review is presented of strain rate history and temperature history effects during the high strain rate deformation of metals with special emphasis on the BCC metals. Possible explanations to account for history effects are reviewed. Experiments are described in which single crystals of aluminum are deformed at various strain rates. Observations
