Abstract : An automated general purpose system for analysis is presented. This system, identified by the aconym 'MAGIC' for 'Matrix Analysis via Generative and Interpretive Computations,' provides a flexible framework for implementation of the finite element analysis technology. Powerful capabilities for displacement, stress and stability analyses are included in the subject MAGIC System for structural analysis. The matrix displacement method of analysis based upon finite element idealization is employed throughout. Six versatile finite elements are incorporated in the finite element library. These are: frame, shear panel, triangular cross-section ring, toroidal thin shell ring, quadrilateral thin shell and triangular thin shell elements. These finite element representations include matrices for stiffness, incremental stiffness, perstrain load, thermal load, distributed mechanical load and stress.
