Design of cylindrical shells using the single perturbation load approach : potentials and application limits

Benedikt Kriegesmann, Eelco Luc Jansen & Raimund Rolfes
The Single Perturbation Load Approach (SPLA) is a promising deterministic procedure on the basis of mechanical considerations to determine reasonable design loads for cylindrical shells in axial compression. In this paper, two main issues are identified that should be understood better in order to appreciate the potential and the limits of application of the SPLA. Firstly, the question whether a single perturbation load in general represents a “worst case” imperfection is addressed. Secondly, the influence...
