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.

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.

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.

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.

[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.

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.

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.

Elastic Characteristics of the Self-expanding Metallic Stents

Investigative Radiology, 1988
We measured elastic properties of the self-expanding metallic (Gianturco) stent using Hooke's law to characterize the stent with respect to its caliber, length, and radius by a coefficient of stiffness. Although this coefficient was independent of the radius of the stent, we found that it was directly dependent on caliber.

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.

Vibration Characteristics of an Elastic Linkage With Elastic Input and Output Shafts

Journal of Mechanisms, Transmissions, and Automation in Design, 1984
This paper develops a mathematical model of the linearized vibrations of a four-bar linkage with a flexible rocker link and flexible input and output shafts. The model assumes constant input velocity and includes inertial masses at the ends of the input and output shafts. The assumed modes technique is used to model the rocker link.
