Elasticity of Demand

The relative stability of a security's or product's price in the face of increased or decreased demand. Elastic securities or products have prices that move as independently as possible from changes in demand. In securities, elasticity is strongly influenced by the number of shares outstanding; if a company has many shares outstanding, a large order to buy or sell them is less likely to affect the price as strongly as a similar order for a company with comparatively few shares outstanding. In other products, elasticity largely comes from whether a given product is considered a necessity or a luxury. A "necessary" product is likely to be more elastic.

Of or relating to the demand for a good or service when the quantity purchased varies significantly in response to price changes in the good or service. For example, the demand for a product with many close substitutes is elastic because a small price rise will cause consumers to switch to competing brands. Compare inelastic.

The elastic deformation energy distribution curve caused by the variation of coal thickness is shown in Figure 5.
In general, time influences stress-strain behavior in biological materials, though, the fruit-rachilla system was considered elastic and isotropic for elastic deformation analysis since it presented a well-defined elastic portion.
The total strain in the Burger's model is a sum of three separate parts; an elastic deformation ([[epsilon].sub.E]), a viscoelastic time-dependent strain ([[epsilon].sub.v]) and an irrecoverable permanent deformation due to viscoplastic flow of the polymer chains ([[epsilon].sub.p]).
(23) developed an intelligent fixturing system, adaptable to variable clamping forces to allow minimum workpiece elastic deformations based on cutter position and dynamic cutting forces.
By contrast, as can be seen in Figure 11(b), the inneratoms would only have a small elastic deformation. The bond breakage of the Ni-2=Sn-3 bond reveals the commencement of irreversible deformation or strain, which is considered as the onset of yielding.
Another cause for the larger elastic deformation of the pulley-cable finger is the high cable force that exerts an external force to the finger frame, causing small elastic deformations of the frame.
The tapping mode use [24, 26, 28] of a nanoprobe, in the configuration of a scanning force microscope, provides a method for measuring elastic deformation. A universal micro-nano-materials tester (UMNT), as manufactured by Bruker-Nano CETR, Inc., is equipped with a NanoAnalyzer (NA)-II test module that contains a ceramic cantilever with a Berkovich diamond tip.
This means that at optimum conditions the control samples (nonreinforced) have a bigger elastic deformation than the rubberised samples (CRM-reinforced SM As) under dynamic traffic loading conditions.
(15) obtained the best results when dental alginate impressions were poured after 10 minutes to avoid distortion from the initial expansion and elastic deformation, but before 1 hour to avoid distortion of the alginate by contraction or expansion due to water imbibition and syneresis.
"This study finds, however, that the ability of the material to resist elastic deformation actually increases with decreasing size."
His contributions to the finite elasticity theory, which explores how materials act during elastic deformation, have led to materials engineering applications.
