elastic force

elastic force

[i′las·tik ′fȯrs]
(mechanics)
A force arising from the deformation of a solid body which depends only on the body's instantaneous deformation and not on its previous history, and which is conservative.

In Figure 5 by keeping the value of the nonlocal parameter and elastic force constant at 0.05 and 0 MPa, respectively and it is drawn in the low-temperature region, where the coefficient of thermal expansion has negative values.
The elastic force in the lattice Boltzmann equation [k.sub.i] is defined as:
The volumetric elastic force density components [nabla] x [sigma] = ([F.sub.x], [F.sub.y], [F.sub.z]) = [F.sub.elastic] of an isotropic medium can be expressed in terms of partial derivatives of the local displacement field as
For the iced messenger wire, the lumped external forces include the elastic forces acted by droppers and the elastic force acted by masts, and the distributed external forces include the damping force and the aerodynamic force.
In this case, the work of the whole system is realized in such way that the mass M does not fluctuate, and the oscillating system with mass m and the spring stiffness k, fluctuates so that elastic force of the spring is equal in magnitude and opposite in direction to the disturbing force [P.sub.0] sin [omega]t .
Typically, these deadweight machines are used to calibrate elastic force transducers (load cells), which output a voltage when a force is applied to the transducer.
Applying the physical principle known as local symmetry to the elastic force law (Hooke's law), this theory (the field theory) formulates all stages of deformation on the same theoretical basis.
It was shown that with the formation of such structures an elastic force develops within the droplets which tends to keep the shape unchanged.
One of the purposes of push-over analysis is determining displacement and elastic force limit.
Although the patterns of both types of mounting technology have similar traits--higher in the corners, lower in the center--the spring/pressure tensioned systems display higher center elastic force and greater range across the whole foil area compared with the mesh-mounted stencils.
