Shear effects during bending of oriented glass-reinforced plastics

An oriented glass-reinforced plastic may be treated as a regular multilayer material. Given large number of layers we can replace the discrete model with a continuous medium whose elastic constants are determined by the properties of the components. Using this approach and assuming that the reinforcing and the resin obey Hooke's law, we examine the problem of the bending of oriented glass-reinforced plastics and by means of two examples demonstrate the importance of shear effects in the bending of beams. The experimental results are in good agreement with theory.Mekhanika Polimerov, Vol 1, No. 2, pp. 38–46, 1965
