elastic deflection

elastic deflection

The deflection of a structural element when a load is applied to it, and which recovers when the load is removed, as opposed to the deflection resulting from creep, 1.

It is accepted practice in many parts of the world to predict the short-term deflection of a flexural member when a load is first applied using standard elastic deflection formulae, incorporating the modulus of elasticity of the concrete [E.sub.c] and an average effective second moment of area [I.sub.ef.av] for the entire span.
What we are seeing is the immediate elastic deflection of the sample (0.150 in.) followed by the viscous deformation of a viscoelastic material.
Knowing the magnitude of elastic deflection z'(t + [DELTA]t), we can be determine the end point [M'.sub.2] position because the direction of z (t + [DELTA]t) was along vector [mathematical expression not reproducible].
In this formulation, the governing equations for large elastic deflection of thin plates are represented by two coupled nonlinear differential equations, known as Von Karamn equations, which are expressed in terms of the displacement w and a stress function F [1]:
Taking advantage of linear elastic deflection, FELA's flexure-based bearings provide frictionless motion.
To ensure proper pavement performance during the period it is designed for, it is essential that there are no plastic deformations in any pavement layer, the continuity of the monolithic layers is not interrupted and the elastic deflection does not exceed the maximum design deviation after applying the design load (Tarawneh, Sarireh 2013).
where [E.sub.w] is the MOE (GPa), P is the difference between the arithmetic average of the upper and the lower limits of applied force in the elastic deformation zone (N), f is the net elastic deflection difference between the measured elastic deflection in the upper and the lower loading limits (m), l is the span (m), b is the cross-sectional width of the test sample (m), and h is the cross-sectional thickness of the test sample (m).
At load with the force [F.sub.0] = 26722 N elastic deflection in mechanical contacts of the bearing would be 37.9 [micro]m.
Elastic Deflection of Wood-Fiberglass Composite Beams.
Bearinx takes into consideration non-linear elastic deflection behaviour of bearings; the elasticity of shafts and axles; and the influence of fit, temperature and speed on bearing operating clearance, preload and contact angle.
