Webflexure: [noun] the quality or state of being flexed : flexion. WebOct 29, 2012 · In-plane bending of curved beams produces substantial through-thickness normal and shear stresses that can result in structural failures. A half-elliptic curved beam, having a known prescribed variable radius of curvature, is studied as an extension of the previously published circular arc beam. michael walters florida
