The different design approaches take the imperfection sensitivity and the scatter of input parameters into account differently. In this paper, the design of a composite cylinder is optimized considering the ply angles as design variables. The KDF concept provides a very conservative design load and in addition an imperfection sensitive design, whereas the other approaches lead to a significantly less conservative design load and to a less imperfection sensitive design configuration. The ways in which imperfection sensitivity is treated by the different approaches and how these influence the optimal design configuration is discussed.en1546-2218Computers, materials & continua2012177-200Design Optimization of Composite Cylindrical Shells under UncertaintyJournal Article10.3970/cmc.2012.032.177http://www.techscience.com/cmc/v32n3/27911Other
