Heart Rate Effects on Strain and Strain Rate in Healthy Children

Journal of the American Society of Echocardiography, 2005
Based on myocardial Doppler echocardiography, regional strain (S) and strain rate (SR) can be evaluated as regional parameters of ventricular function. The use of these techniques in clinical pediatric cardiology remains a challenge. This study establishes reference values for S and SR in both systole and diastole in healthy children over a large age ...

Strain-rate effects for high-strain-rate computations

Journal de Physique IV (Proceedings), 2006
This paper examines the effect of strain rates for computations involving high strain-rates, beyond 10 3 s -1 . Although it is generally agreed that there is an enhanced rate effect at these higher rates, there is uncertainty regarding the interpretation of dynamic test data, the form of the high-rate effect, and the effect of the high rates on ...

Strain-Rate Effects in Metals

Journal of Applied Physics, 1966
A series of computations has been completed which investigates strain-rate effects on stress-wave propagation in metals. The principal difficulty in calculations of this type is the choice of a functional relationship between stress, strain, and strain rate.

Effect of Strain Rate on the Stress-Strain Behavior of Sand

Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2011
Drained triaxial compression tests on crushed coral sand were performed from near-static strain rates to very high strain rates (up to approximately 1,800%/s). Experiments were performed on dry, vacuum-confined axisymmetric specimens at two different confining pressures (98 and 350 kPa) and two different densities (Dr approximately 36 and 60%).

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.

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.

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.
