Buckling of composite circular cylindrical shells with random material properties

摘要

Composite materials exhibit a scatter in their properties. This is generally ignored in conventional structural analysis leading to results that may be non-conservative. The present study discusses the critical buckling analysis for circular cylindrical shells of laminated composites incorporating the effects of randomness in the material properties. A perturbation approach has been employed to develop expressions for the mean and variance of the critical buckling load in terms of material property statistics. Working of the approach has been illustrated with an example.
