An Estimation of Dynamic Modulus of Elasticity in Cantilever Flexural Timber Beams
Drvna Industrija, 2014 Due to considerable influence of shear deflection and rotary motion, the modulus of elasticity is hardly obtainable in fixed-free flexurally-excited (cantilever) beams. For isotropic materials, Timoshenko has proposed a set of curves to correct the fixed-

Flexural phonons in free-standing graphene [PDF]
, 2007 Rotation and reflection symmetries impose that out-of-plane (flexural) phonons of free-standing graphene membranes have a quadratic dispersion at long wavelength and can be excited by charge carriers in pairs only.
