Elastic Deformation

elastic deformation

[i′las·tik ‚dē·fər′mā·shən]
(mechanics)
Reversible alteration of the form or dimensions of a solid body under stress or strain.

Elastic deformation

The deformation that occurs instantly when a load is applied and is instantly and fully recovered when the load is removed.

Elastic Deformation

 

a deformation that disappears when the load is removed. Such deformation requires that the elastic limit not be exceeded. If the limit is exceeded, the deformation is permanent.

elastic deformation

A change in shape without impairment of the elastic properties of a material.

It can be seen from Figure 4 that the slope angle [theta] of erosion zone has a great influence on the distribution of the elastic deformation energy when the coal thickness is constant.
From the analysis of the previous section, the mode shape function with pinned-free boundary conditions of the flexible intermediate link is used to discrete elastic deformation. As can be seen from [24], the modal functions under the pinned-free boundary condition are shown as follows:
The [E.sub.K] parameter corresponds to the instantaneous elastic deformation and is associated with elastic modulus of the Maxwell spring that increased from 2.1 GPa to 3.4 GPa by addition of 2 wt% of CNC particles.
then it is possible, in principle, to determine the boundary displacement, [zeta], at which - given the clamping force [F.sub.n] - the contact between clamping element and workpiece is maintained within the domain of elastic deformations. Let us assume that, for a range of clamping force values, [F.sub.n], and various contact interface features, relation (1) takes the form of a family of regression lines, as shown in Fig.
Whereas a very sharp tip radius and nanometer-scale elastic deformation could clearly present the need to consider modeling of near-atomic interactions, the use of a classic modeling approach as presented for Hertzian tests is generally consistent with the actual diamond tip condition where the contact radius is less than 5% of the tip radius.
Thus, the modified binder become more elastic and thus improved its resistance to elastic deformation under high tensile stress [1-3].
The impression requires elastic deformation as it is removed from the mouth; however, permanent deformation can be minimized if the material has a sufficiently high elastic limit.
Strength is discussed in the first part of the book without reference to equations of elastic deformation. However, the designer is concerned also with stiffness, for which elastic analysis is needed, and the standard equations are presented.
Brown took the polymer particles to be entirely solid, deformable only elastically, i.e., reversibly, and not at all viscously; he overlooked any elastoviscous contribution to a particle's resistance to elastic deformation. Eckersley and Rudin (9) pointed out that whereas Brown considered only elastic deformation of particles, their deformation might be viscoelastic, like bulk polymer that lacks crosslinking.
It has been suggested that the thrust plate undergoes elastic deformation due to axial loading.
"Children often tend to twist their finger when placing the finger on the scanner, creating an elastic deformation which provides a great testing ground for our technology."
The sample was then unloaded back to five percent of the ultimate compressive strength and the value of the elastic deformation ([[epsilon].sub.e]) was determined.
