Flexural

Part of speech: adjective

Definitions

1. Relating to bending or the ability of a material or structure to curve under pressure or force ; pertaining to the deflection or deformation caused by applied load to beams or other elements ; connected to the mechanical behavior observed during bending stress
2. Concerning the property or action of bending without breaking in materials or structures ; associated with the stress distribution and strain response in objects subjected to load causing curvature ; describing the mechanical characteristics involved when an element undergoes bending deformation
3. Referring to the flexing action or bending response of physical bodies under force ; involving the examination of stresses and strains arising from bending moments ; linked to the study of how materials or components behave when loaded to produce curvature rather than linear compression or tension

Etymology: "Flexural" is a plain technical formation: the noun "flexure" (from Latin "flexura," a bending, from "flectere," to bend) with the adjectival suffix "-al" attached. The suffix itself has a long pedigree, passing into English through Old French and Middle English, and it is the same ending that turns many nouns into adjectives such as "natural" or "dental." The base "flexure" entered English as a term for the act or state of bending, and over time it came to mean a curved shape or a degree of bend. "Flexural" therefore names the quality of bending itself, and in engineering it is the word for behaviour under bending load, as in "flexural strength" or "flexural stress." The word is a straightforward coinage built on existing parts, so its interest lies mainly in how precisely it narrowed to a technical sense.
