Using intense plastic straining for high-strain-rate superplasticity
JOM, 1998Ultrafine grain sizes may be introduced into bulk samples by using the intense plastic straining technique equal-channel angular pressing. This article describes the principles of equal-channel angular pressing and demonstrates the application of this procedure to attain ultrafine grain sizes in an Al-3Mg solid-solution alloy and a commercial cast Al ...

Thermal and Cardiovascular Strain from Hypohydration: Influence of Exercise Intensity
International Journal of Sports Medicine, 1998This study determined the effects of exercise intensity on the physiologic (thermal and cardiovascular) strain induced from hypohydration during heat stress. We hypothesized that the added thermal and cardiovascular strain induced by hypohydration would be greater during high intensity than low intensity exercise.

Stress and strain in a plate subjected to intensive drying
Journal of Engineering Physics and Thermophysics, 1992The study was carried out to investigate the development of a stress-strain state in a thin porous plate subjected to intensive drying. A narrow evaporation zone (an evaporation front) divides the plate into two regions with different structures and rheological behavior.

The strain intensity criterion for crack branching in ceramics
Engineering Fracture Mechanics, 1978Abstract Using a fracture mechanics method, crack branching data from three investigations were put on a comparable basis and used to demonstrate a strong correlation between the stress intensity at crack branching and Young's modulus. This strong correlation suggests a strain intensity criterion for crack branching at sharp cracks in brittle ...

Degree of magnetic anisotropy as a strain-intensity gauge in a saturated finite-strain zone
Journal of the Geological Society, 2009Abstract: Anisotropy of magnetic susceptibility (AMS) analyses were carried out on mylonitic quartzites from the footwall of the Main Central Thrust Zone, Garhwal Higher Himalaya, India. A systematic increase in degree of magnetic anisotropy ( P ′) with distance from the Main Central Thrust is documented ...

Active structural intensity control using strain sensing
The Journal of the Acoustical Society of America, 2000An investigation of structural intensity control using strain sensing is presented in this paper. As opposed to previous work, the approach taken here does not assume waves propagating predominantly in one direction. Moreover, the instantaneous intensity is completely taken into account in the control algorithm, i.e., all the terms are considered in ...

Dependence of dynamic yield point of strain rate intensity
Strength of Materials, 1991A modified method is described for determining dynamic yield strength under conditions of a nonuniaxial stressed state with high strain rates suggested by Taylor which is based on measuring the distribution of residual strains in a cylinder after impact of it with a rigid barrier.

Intensity of Halothane- and Hypercapnia-Induced Cerebral Hyperemia Is Strain-Dependent in Rats
Anesthesia & Analgesia, 1996Cerebrovascular responses to physiologic and pharmacologic stimuli vary between laboratories using different strains of the same species. We tested whether the cerebral blood flow (CBF) response to 1% halothane or hypercapnia is strain-dependent in rats.

An Effect of Plastic Anisotropy on the Strain Rate Intensity Factor
ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 2, 2010The strain rate intensity factor in the theory of rigid perfectly plastic isotropic materials is the coefficient of the principal singular term in a series expansion of the equivalent strain rate in the vicinity of maximum friction surfaces. This coefficient can be used to predict the evolution of material properties in a narrow layer in the vicinity ...

Rain exacerbates cold and metabolic strain during high-intensity running
The Journal of Sports Medicine and Physical Fitness, 2019Outdoor exercise often proceeds in rainy conditions. However, there are very few studies reporting the physiological effects of cold with rain or wet-cold exposure on humans during exercise. The purpose of this study was to investigate the effects of rain on physiological responses during running exercise at 80% V̇Omax in the cold.Twelve healthy men ...
