Abstract

This paper provides the results of an investigation into the reliability of optimized shells obtained using shape and size optimization and based on linear elastic small displacement Reissner-Mindlin (RM) shell models. The various tools utilized are described: computer aided geometric design (CAGD), automatic mesh generation, finite element (FE) analysis, design sensitivity analysis and mathematical programming. Once the optimal shape and thickness distributions of the shell have been determined, the nonlinear buckling loads of the initial and optimized shells are investigated using a geometrically nonlinear analysis tool capable of dealing with complex load-displacement paths including snap-through and snap back.
