Abstract
Several theoretical procedures are proposed to extract unidirectional ply properties from the results of dynamic tests on angle ply laminates. The tests were carried out on filament wound tubes under hoop loading. It has been shown that the response of certain laminates is dominated by particular ply properties which can be isolated and ex tracted with accuracy. The extracted properties include longitudinal, transverse and in- plane shear moduli and strengths. The procedures are based on conventional 2D laminate analysis with extensions to cater for lamina non-linear and progressive failure behaviour. These procedures are equally valid for static or dynamic test data. Full descriptions of methodology and computational flow charts are presented.
