Century Dictionary and Cyclopedia
    • n flexure The act of bending, or the state of being bent; a bending; specifically, in mech., a strain in which certain planes are deformed into cylindrical or conical surfaces. There is a so-called neutral plane which is neither stretched nor compressed. The planes parallel to it on one side are compressed; those on the other side are stretched. In geometry flexure differs from curvature only in being always non-quantitative, while curvature is sometimes used quantitatively.
    • n flexure The part bent; a bend; a fold.
    • n flexure Obsequious bowing or cringing.
    • n flexure In geology, the folding or bending of strata under compression.
