Abstract : Initial imperfections have a substantial effect on the behavior of thin elastic shells subject to a load. The large spread of experimental critical forces is due to these imperfections. The report treats initial deflections as a random field. Assumptions are introduced on the smallness of the deflection scale and the scale of their correlation compared with the characteristic middle surface measurements; there is also one for the homogeneity of the initial irregularity field. Equations obtained by linearizing shell theory equations in the initial stage region are used. (Modified author abstract)
