On the dynamic buckling of stochastically imperfect finite cylindrical shells under step loading

Abstract

The dynamic buckling load of stochastically imperfect finite right circular cylindrical shells subjected to step loading is determined by means of regular perturbation procedures .The imperfection is assumed to be a Gaussian random function of position and consequently is homogeneous. The result obtained is implicit in the load parameter and is asymptotically valid for small magnitude of the random imperfection, which is itself taken as the first term in a Fourier sine expansion.
