A study is presented of the effect of initial deviations on the load carrying capacity of thin circular cylindrical shells under uniform axial compression. A perturbation expansion is used to reduce the nonlinear equations of von Karman and Donnell to an infinite set of linear equations, of which only the first few need be solved to obtain a reasonably accurate solution. The results for both infinite shells and shells of finite length indicate that a small imperfection can sharply reduce the maximum load that a thin-walled cylinder will sustain. In addition, for a particular set of boundary conditions, it is shown that the effect of the length of a finite shell is small as far as the load carrying capacity is concerned, but significant when the number of waves around the circumference has to be determined. A further result of the study is that axisymmetric initial deviations reduce the load carrying capacity only slightly more than deviations characterized by a product of trigonometric functions of the axial and circumferential coordinates if the wave lengths are properly chosen.

Abstract This work presents the experimental and finite element simulations to investigate the behavior of both unstiffened and anisogrid composite lattice cylindrical shells under low velocity axial impact. Impact damage has been an epidemic problem for composite structures. Even subjected to a low velocity impact, composite may sacrifice its load carrying capacity considerably due to various modes of failure. The test coupons fabricated as per American Society for Testing of Materials (ASTM) standards were put through Infrared (IR) thermography to find the imperfections during fabrication. The test coupons without defects were only taken into account for material characterization. Finite Element simulations are carried out on both the unstiffened and anisogrid shell structures using LS-DYNA® for a series of low velocity impacts. Also these shell structures were subjected to impact load experimentally for the validation of the results. The results of these studies indicate that the anisogrid model presented in this work possess greater load carrying capacity than unstiffened shell under dynamic loading conditions, also the weight of the structure has been drastically reduced.
