Curvature of beam under pure bending
WebAlso, the radius of curvature Rx, Fig. 6.2.2, is the reciprocal of the curvature, Rx 1/ x. Fig. 6.2.2: Angle and arc-length used in the definition of curvature As with the beam, when the slope is small, one can take tan w/ x and d /ds / x and Eqn. 6.2.2 reduces to (and similarly for the curvature in the y direction) 2 2 2 http://emweb.unl.edu/NEGAHBAN/Em325/11-Bending/Bending.htm

(2024) carried on a three-point 3000 h bending creep tests on the r of one-web and two-web FRP-balsa sandwich beam with loads of 20%, 40%, 60% and 80% of the beams’ ultimate bending capacities. The tests results showed that the addition of the webs effectively prolongs the creep failure time and improves the creep deformation.
