Locking of the strain rate effect in Hopkinson bar testing of a mild steel

International Journal of Impact Engineering, 2019
The flow stress of many metals exhibits a dependence on the strain rate, in the form of a dynamic amplification of the static flow stress which, according to most literature models, saturates at the strain rates typical of Split Hopkinson Tension bar ...

Strain Rate Effects on Ultimate Strain of Copper

1979
Abstract : The strain-rate effect on strain to failure of copper was experimentally investigated. Both Oxygen Free High Conductivity (OFHC) copper and Electrolytic Tough Pitch (ETP) copper were studied. Ultimate strains were measured for a range of strain rates from 0.0001 strain/second to over 10000.0 strain/second.

The Effect of Strain Rate on Diffusion Flames. II: Large Straining

SIAM Journal on Applied Mathematics, 1976
When two initially unmixed reactants are allowed to react, the rate of consumption of reactants, the enthalpy distribution and the features of the resulting diffusive combustion process depend in a significant way on the kinematics of the flow field occupied by these reactants.

Effect of strain and strain rate on fatigue‐accelerated biodegradation of polyurethane

Journal of Biomedical Materials Research Part A, 2003
AbstractA diaphragm‐type film specimen was used to study in vitro degradation of poly(etherurethane urea) (PEUU) under conditions of dynamic loading. This geometry allowed both uniaxial and biaxial loading in a single experiment. During testing, the film was exposed to a H2O2/CoCl2 solution that simulated in vivo oxidation of PEUU.

Strain-rate sensitivity and effects of strain rate in sheet forming

Metals Technology, 1980
AbstractThe strain-rate dependencies of flow strength and strain-hardening behaviour are particularly important in sheet-forming operations because they influence strain distribution and necking resistance. Measurements made in uniaxial and biaxial tensile tests on low-carbon steels have shown that strain-rate sensitivity is a function of both strain ...

Effects of strain rate on the behavior of elastomeric impression

The Journal of Prosthetic Dentistry, 1991
The effects of strain rate on the ultimate tensile strength, ultimate elongation at fracture, and elastic recovery of five commonly used elastomeric dental impression materials were studied. Each specimen was prepared by standard mixing techniques, placed for setting in a standard ASTM mold, removed, trimmed, and mounted in an Instron testing unit ...

Crashworthiness analysis of foam–filled square column considering strain rate effect of the foam

Thin-walled structures, 2018
This 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.

Experimental and numerical investigations on seismic responses of reinforced concrete structures considering strain rate effect

Construction and Building Materials, 2018
The strain rate effect can inevitably impact the seismic responses of reinforced concrete (RC) structures because the dynamic properties of RC materials under earthquakes change significantly with the time-varying loading rates.

The effect of strain rate on a premixed laminar flame

Combustion and Flame, 1986
The structure of a strained premixed laminar flame is examined. The flame is formed in the vicinity of a stagnation point established by the counterflow of fresh mixture and hot combustion products. This ideal configuration analyzed by Libby and Williams [18] with activation energy asymptotics is here examined numerically.

Strain rate effect on the failure properties of tendons

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2004
The 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.
