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
