Elastic Characteristics of the Ureter

Journal of Urology, 1975
An explanation was sought as to why the ureter becomes tortuous with increased intraluminal pressure. Changes in ureteral diameter and length, secondary to increased intraluminal pressure, were measured in different pathologic conditions and these changes were compared to similar ones in a non-biologic material (latex rubber tubing).

Elastic characteristics of the airway wall

Journal of Applied Physiology, 1989
To examine the elastic behavior of the upper airway, we obtained pressure-area plots from data gathered from acoustic images of the airway and measurements of mouth pressure during tidal breathing in 10 adult human volunteers (dA/dP). These plots revealed both tidal hysteresis and a change in slope as a function of distance along the airway. The slope

Elastic deformation characteristics of the spine

Journal of Biomechanics, 1971
Abstract A survey of some of the significant contributions in the area of experimental studies on the strength of the vertebral column is made. A short history on the experimental work with intact human cadavers is then given, leading to a discussion on the significance of bending stresses in the vertebral column during caudocephalad acceleration ...

Synthesis of Elastic Characteristics Based on Nonlinear Elastic Coupling

2021
Modern equipment and units operate in a wide range of loads, amplitudes, and vibrational frequencies caused by harmonic, shock, or external influences. On this basis, it is urgent to develop new designs with advanced capabilities to counteract torsional vibrations in the technical system.

Scattering characteristics of elastic waves by an elastic heterogeneity

Geophysics, 1985
Abstract Elastic wave scattering by a general elastic heterogeneity having slightly different density and elastic constants from the surrounding medium is formulated using the equivalent source method and Born approximation. In the low-frequency range (Rayleigh scattering) the scattered field by an arbitrary heterogeneity having an ...

Force-extension characteristics of orthodontic elastics

American Journal of Orthodontics, 1977
The force-extension characteristics for a wide range of elastics were determined. It was found that (1) selection of elastics were determined. It was found that (1) selection of elastics based on 3 x lumen size will probably result in more force being generated than was previously reported, (2) there is very little difference seen in force-extension ...

Determination of Elastic Wing Aerodynamic Characteristics

Journal of the Aeronautical Sciences, 1952
The basic aeroelastic integral equation is formulated by treating the wing as a tapered cantilever beam mounted normal to its straight elastic axis. By means of an iterative process, a series solution is obtained for the aeroelastic change in angle-of-attack distribution. For sweptback wings, this Neumann solution fails to converge at dynamic pressures

Elastic characteristics of elastomers

Journal of Applied Mechanics and Technical Physics, 1992
Two characteristics are introduced for eiastomers subjected to uniaxiai tension: Poisson's ratio ~ and the initial modulus Etr. For ten types of rubbers employed in shoes [i], these quantities are constant right up to fracture deformations, it is shown that the shear modulus G, Young's modulus E, and the bulk modulus K of rubbers can be calculated from

Promotional Elasticities and Category Characteristics

Journal of Marketing, 1996
The authors study the relationships between product category characteristics and average brand promotional elasticity within the category. They present a framework for understanding these relationships and use it to generate hypotheses. The authors also consider three types of promotions and seven category characteristics.

On Elastic Continua With Hereditary Characteristics

Journal of Applied Mechanics, 1951
Abstract In a previous paper (1) the free and forced vibrations of systems of one degree of freedom with hereditary damping characteristics were discussed. In the present paper the classical equations of motion for elastic media are extended on the basis of the general linear stress-strain law involving hereditary damping.
