The bending of clamped beams made of materials with low resistance to shear

Oriented glass-reinforced plastics have low resistance to shear. This means that the calculation of beams made of these materials on the basis of the hypothesis of plane cross sections is not possible. We compare several methods of calculating shear and verify them on the basis of experimental data obtained for beams made of oriented glass-reinforced plastics with one or both ends clamped. We also discuss the boundary conditions in the clamped cross section and the effect of axial force in the case of fixed supports.Mekhanika Polimerov, Vol. 3, No. 4, pp. 730–736, 1967
