This paper examines the influence of a through crack on the overall flexural behaviour of a layered composite Carbon Fibre Reinforced Polymer (CFRP) plate that is fixed boundary along a circular boundary. Plates with different through crack configurations and subjected to uniform air pressure loading are examined both experimentally and computationally. In particular, the effect of crack length and its orientation on the overall pressure-deflection behaviour of the composite plate is investigated. The layered composite CFRP plate used in the experimental investigation consisted of 11 layers of a polyester matrix unidirectionally reinforced with carbon fibres. The bulk fibre volume fraction in the plate was approximately 61%. The stacking of cracked laminae is used to construct a model of the plate. The experimental results for the central deflection of the plate were used to establish the validity of a computational approach that also accounts for large deflections of the plate within the small strain range.
