Reports of three related studies germane to structural optimization are provided. The first describes virtual memory simulator suitable for management of large quantities of numerical data such as required for sparse matrix manipulation. The second report describes two sparse matrix processors suitable for the large equation systems arising in structural analysis and provides comparative results. The last report describes a study of two optimization algorithms in the context of structural optimization. A number of test results for parameter studies and a general comparison of the two algorithms are given.

There is a tendency of the critical load to become unstable if the lowest buckling modes are simultaneous or nearly so. This tends to be the case if structural panels are optimized with bifurcation buckling constraints. A complete software package, POIS (Panel Optimization with Integrated Software), was developed to solve this problem. POIS is described in a separate report with a summary presented here. The pre-buckling nonlinear behavior due to geometric imperfections is taken into account. The procedure allows optimization with the collapse load as constraint for panels that buckle locally well below the ultimate load. The computer programs are verified by application in some practical cases involving metal and composite material panels. It is concluded that the most weight - efficient design is one in which local buckling is permitted. A supplementary experimental program should be executed before POIS can be qualified as a reliable instrument for panel design. (Author).

Numerical Procedures For Analysis Of Structural Shells written by and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1981 with Finite differences categories.
An evaluation is undertaken of currently used discretization procedures in numerical analysis of structures. Emphasis is on the nonlinear behavior of thin shells and plates. It is found that the computer economy is extremely sensitive to the choice of element configuration. A proper balance between the order of the approximations of inplane and lateral displacements is important. The best finite element procedures are superior to finite differences for bifurcation buckling and for moderate nonlinearity. However, for shell collapse analysis the finite differences approach is quite superior to the finite elements. Suggestions are made for improvement of finite element technology for structures undergoing large rotations.

This book is aimed at informing organic chemists and natural products chemists on the use of NMR for structure elucidation to enable them to ensure they yield the most reliable possible data in the minimum possible time. It covers the latest pulse sequences, acquisition and processing methods, practical areas not covered in most texts e.g. detailed consideration of the relative advantages and disadvantages of different pulse sequences, choosing acquisition and processing parameters to get the best possible data in the least possible time, pitfalls to avoid and how to minimize the risks of getting wrong structures. Useful in industrial, pharma or research environments, this reference book is for anyone involved with organic chemistry research and, in particular, natural products research requiring advice for getting the best results from the NMR facilities.
