Structural Optimization of Shells of Revolution and Prismatic Shells
2003Chapter 6 deals with structural shape and thickness optimization of SORs and prismatic shell structures. The basic algorithm for SSO is described first. Basically, SSO procedures involve the efficient integration of structural shape definition, automatic mesh generation, structural analysis, sensitivity analysis and mathematical programming methods ...

Shell Structure of Exotic Nuclei
2008A basic introduction to the nuclear shell model is presented, with illustrative explanations of shell-model concepts and procedures. All details of many-body theories are avoided. First, we explain how magic numbers and shell structures appear from fundamental properties of nuclei such as the short-range attractive interaction and density saturation ...

The radial density D(r) is computed from analytical Hartree-Fock wavefunctions for the first 54 elements of the periodic table. The calculations exhibit the familiar picture of spherical shells of electron density for the first three periods but for the fourth and fifth periods an ambiguity in the shell structure is observed. This ambiguity is analysed

Formulae are given for the bending and shear stress in a long shell structure such as an aircraft wing, together with formulae for the different modes of buckling. These are used in the optimization of some reinforced shell structures. Alternative methods for modelling the reinforcement are discussed. At higher stresses, yielding of the material causes
