Abstract
SummaryA theoretical and experimental study is made of the stresses and strains around circular holes in plates reinforced with carbon fibre filament-wound discs. An analytical solution is given for infinite isotropic plates subjected to uniform tension, but for orthotropic carbon fibre plates the finite-element displacement method of analysis is used. The filament-wound discs are found to be efficient in reducing the stresses around the holes with the principal stresses being taken, in the main, by the strong fibres. There is reasonable agreement with the experimental results for the uniform tension cases, but results from tests on bolt-loaded holes do not correlate as well with theory.
