Elastic characteristics of fibrous metals

Soviet Powder Metallurgy and Metal Ceramics, 1968
1. The relationship between the modulus of elasticity E and relative density ϑ of fibrous metals is described by Eq. (2), in which the minimum value of the power m is close to 2. 2. The contact ultimate strength obc=ob/α=obEc/E for fibrous copper and stainless steel, determined from Eq.

Elastic characteristics of branched‐network polymers

Journal of Applied Polymer Science, 1996
The computed dependencies of elastic characteristics of branched-network polymers were obtained on the basis of the Takayanagi series model. The moduli ratio (γ) for branched-network and branched polymers increases as a result of an increase of the moduli ratio of network and branched phases (E* net /E* br ) and the network phase fraction (V net ).

Elastic Characteristics of Moorings

Journal of the Waterways and Harbors Division, 1967
The weight, strength, and elastic properties of steel-wire and fiber mooring ropes are examined for purposes of predicting their elastic behavior under dynamic conditions. Most of the essential properties can be generalized by empirical formulas that apply to all ropes when the appropriate values of certain constants are known.

Elastic characteristics of the lung perivascular interstitial space

Journal of Applied Physiology, 1983
An analysis of the elastic behavior of the lung perivascular interstitial space during interstitial fluid accumulation is presented. Fluid accumulation must deform the lung parenchyma and vascular walls that form the interstitial space boundaries.

[Visco-elastic characteristics of the rat aorta].

Bollettino della Societa italiana di biologia sperimentale, 1979
In order to estimate wave propagation "in vitro", aortic compliance has been studied by means of rings and stripes from 6 adult male Wistar rats. Lengthening and shortening maneuvres have been performed; the pulse transmission rate was evaluated by calculating the elastic modulus during the maneuvres. A Norepinephrine infusion has been done.

Compliance of single joints: elastic and plastic characteristics

Journal of Neurophysiology, 1988
1. Step changes in torque were applied to the elbow or ankle joint of normal human subjects who exerted constant levels of effort. They were instructed to not react to the torque but to allow their limbs to move to a new equilibrium position. In this experimental paradigm, the joint may be characterized by a nonlinear compliant element.

Research of power modulation characteristics of elastic actuators

2017 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2017
Elastic actuator is one type of advanced actuators composed by the traditional stiffness actuator and the transmission mechanism with more than one elastic elements. It is also the core component with the function of achieving motion, force and energy transformation in various robot systems.

Estimates of the elastic characteristics of graphenes

Physics of the Solid State, 2009
The central and noncentral force constants have been calculated within the previously proposed model of the binding energy of carbon atoms in graphene, which is based on the Harrison bonding orbital method. The results obtained have been used to estimate the characteristic phonon frequencies and elastic constants of graphene materials.

Elastic properties of interfaces. Elasticity moduli and spontaneous geometric characteristics

Journal of the Chemical Society, Faraday Transactions 2, 1989
An arbitrarily organized interface with non-uniform curvature is considered. The force factors (surface tension and bending moments) depend on interface geometry. The general definitions of spontaneous geometrical characteristics and elastic moduli of interface are presented.

On the elastic characteristics of graphene and silicene

Physics of the Solid State, 2010
Analytical expressions for the central k0 and noncentral k1 force constants of two-dimensional (graphene, silicene) and three-dimensional (diamond, silicon) structures have been obtained within the previously proposed model of the binding energy of carbon atoms in graphene.
