The phrase "a surface deflection" is correct and usable in written English.
It can be used in contexts related to engineering, physics, or materials science, particularly when discussing the bending or deformation of a surface under load.
Example: "The engineers measured a surface deflection of 5 millimeters under the applied weight."
Alternatives: "a surface deformation" or "a surface displacement".
We present a new numerical model to calculate the surface deflection of a two-dimensional, yet variable thickness, thin elastic plate.
We also use the oil stoning method to make a subjective evaluation on surface deflection in the sample panel.
A major problem with the evaluation of surface deflection is that panels are evaluated manually and to a great extent subjectivity is involved.
It indicates that the proposed system is able to provide a tool for an accurate and efficient measurement of the surface deflection and evaluation of the deterioration of asphalt pavements under moving loads.
The theory has been applied using a typical variable-incidence missile by placing a realistic restriction on the mean-square surface deflection so that the system operation is confined to the linear range.
Pavement surface deflection basins induced by a 40 kN (9-kip) FWD applied load were used to estimate the values of the elastic modulus for the subgrade and the stiffness of the springs used to model the load transfer at the joints.
Up to now various methodologies have been applied based on the surface deflection bowl obtained under either a known moving wheel load or devices such as falling weight deflectometer.
This paper analyses the hydrodynamic efforts generated on an AUV considering the combined effects of the control surface deflection and the angle of attack using CFD software based on the Reynolds-averaged Navier Stokes formulations.
The basic equation that relates maximum surface deflection to the static wheel load for a one-layered system is provided in Eq. 11a.
The flow simulations have shown that the occurrence of the control surface stall depends on a linear relationship between the angle of attack and the control surface deflection.
