Book Description
Extensive comparison studies were run on different idealizations and on the use of different types of finite elements for the analysis of a single spar, a rectangular section box beam, a multispar swept wing and a centrally loaded rectangular plate. The results indicate that the principle of a dual analysis, with its capability to provide upper and lower bounds to the structural deflections, is of practical value. Convergence in the deflection pattern, from above and from below, is equally satisfactory. Convergence and evaluation of the stress output is sometimes more difficult. However, the more sophisticated elements generate stresses that are simpler to interpret and less sensitive to the geometrical subdivision pattern. The report contains the theory of the conforming displacement models and stress-diffusing equilibrium models required for obtaining strain energy bounds, with a description of the models that were operational in the numerical studies. It also contains a description of the ASEF, direct stiffness type, program.

Book Description
An automated general purpose system for analysis is presented. This system, identified by the acronym 'MAGIC' for 'Matrix Analysis via Generative and Interpretive Computations', provides a flexible framework for implementation of the finite element analysis technology. The subject document, Volume II, contains instructions for the preparation of input data and interpretation of output data with examples drawn from the applications presented in Volume I.
