SUMMARY Theoretical analyses are made of the influence of the following features on the longitudinal shear and transverse tensile moduli of unidirectional fibre reinforced composites: (i) random variations in positioning of individual fibres, (ii) overall variations leading to fibre bunching, (iii) overall variations leading to interspersed matrix layers, (iv) localised variations resulting in ...

SUMMARY The variability of fatigue damage from flight to flight is examined for a fleet of aircraft, both within aircraft and between aircraft. A method is described of modifying the standard analysis of variance technique to take account of correlation between consecutive flights and an example is given. It is then shown how to use the estimates of variance so obtained in the derivation of fac...
