Abstract

A theoretical and experimental approach to an investigation of transient loading and deformation of composite beams and plates was developed for the purpose of creating structures best resisting impact loading. The problem of transverse impact on beams and plates is formulated and solved on the basis of the finite-element method with the use of Timoshenko's shear theory and finite-difference method for orthotropic composite plates. The experimental investigations were conducted by means of a strain-gauge complex. It is shown experimentally and by calculations that minimum deformations under transverse impact are realized for reinforcement angles approaching the transversal isotropic scheme of placing fibers in layers of the composite, and fracture should be expected in the form of delaminations near the impact site and near the support fastenings.
