Lightweight design is an important aspect in the development of components to reduce material use and obtain energy-efficient structures. Frequently, lightweight structures are designed for one or a few load cases. Therefore, optimized designs can be less robust against changes in boundary conditions, scattering material parameters or deviating tolerances. Thus, these structures must be designed with safety factors that counteract the targeted lightweight design goal. In this article, an approach for the consideration of uncertainties is presented. The approach allows evaluating potentials of the accurate consideration of uncertainties. Finally, the developed approach is implemented for the calculation of the buckling load and torsional strength of thin-walled CFRP cylinderical shells.
Efficient and systematic design methods are indispensable aids on the way to effective lightweight solutions. In this article, the necessity of providing the product developer with a design method for the design of endless fibre-reinforced plastic (FRP) components to fulfil fatigue requirements is highlighted. Existing damage models and test methods could be used and extended within such approaches. A suitable method should take into account particularly the variety of requirements for FRP components and consider other influences, e.g. from multi-layer composite design or load introduction, preferably supported by CAE tools. The simple applicability of an effective approach should be demonstrated both on test specimens and on demonstrator components.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
