摘要：

A new, non-probabilistic method is developed in this study to predict the variability in buckling loads of composite plates and shells stemming from the unavoidable scatter in elastic moduli. The available measurements of elastic moduli are fitted by the four-dimensional uncertainty 'box' and appropriate ellipsoid. For the specific cases considered, the maximum buckling load of the composite plate exceeds by 11% the value of the buckling load based on the calculation using the nominal values of elastic moduli. In the case of the cylindrical shell, an appropriate exceedance constitutes 9%.
