Crashworthiness analysis of foam–filled square column considering strain rate effect of the foam
Thin-walled structures, 2018This paper presents results on the crushing behavior of aluminum foam–filled columns with square cross section. Here, the effect of inserting an aluminum foam to single–walled and double–walled columns were studied.

Strain rate effect on the dynamic tensile behaviour of flax fibre reinforced polymer
Composite structures, 2018Flax fibre reinforced polymer (FFRP) has been heavily studied in terms of static properties. To study its dynamic behaviour, experimental work also needs to be carried out. This study presents the tensile properties of flax fibre reinforced polymer (FFRP)

Strain rate effect on the failure properties of tendons
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2004The purpose of this study is to evaluate the effect of strain rate on the failure properties of tendons. Seventy-five chicken flexor digitorum profundus (FDP) tendons were tensile tested at 15 strain rates, ranging from 0.05 to 150 per cent/s. Results showed that strain rate had little effect on the shape of the stress-strain curve.

Strain Rate Effects in Composites
Applied Mechanics Reviews, 1997A review of the high strain rate behavior of filamentary composite materials is presented. The experimental techniques used for evaluating the dynamic performance of composites are discussed, as well as results obtained by researchers for various types of filamentary composites. Areas of research needed for expanding the information base for composites

Strain Rate and Strain Rate History Effects in Two Mild Steels.
1979Abstract : 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

The effects of strain and strain rate on residual microstructures in copper
Proceedings, annual meeting, Electron Microscopy Society of America, 1986The strain rate sensitivity of a variety of materials is known to increase rapidly at strain rates exceeding ∼103 sec-1. This transition has most often in the past been attributed to a transition from thermally activated guide to viscous drag control. An important condition for imposition of dislocation drag effects is that the applied stress, σ, must ...

Strain Rate Effects in Tungsten
JOM, 1956The yield strength of annealed tungsten was found to have a strain rate exponent 12 times as great as that of low carbon steel. The effects of temperature and strain rate could be correlated through the Zener-Hollomon parameter with a heat of activation as-sociated with yielding of 32,000 cai per g-atom. This heat of activation is independent of strain

High strain rate effects on the strain of alloy steels
Journal of Materials Processing Technology, 1999Abstract The effect of high strain rates in both compression and torsion was studied on several micro-alloyed steels. The high strain rates were obtained using both a torsion and a compression Split Hopkinson Bar, which are capable of producing strain rates in excess of 10 3 s −1 .

Decrease of stress level at a given strain with increase of strain rate is discussed in terms of three theories: the Johnston-Gilman theory of yield and flow, diffusional aging mechanisms, and stress induced structural instability. None of these theories explain inverse rate effects.

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 ...
