Paper Abstract

Holographic interferometry has been used to measure the deflection of thin CFRP cross-ply plates under very small pure bending loads. The paper describes the design and calibration of the optical system, the method of mounting and loading the specimen, and the computation of curvature values from the fringe data, together with a brief section on the subsequent derivation of the bending stiffness. Results obtained, both for the composite material and for a control plate of aluminium alloy, are shown to be in good agreement with theory, and further applications to thick plates and those of unknown construction appear feasible.
