Engineering Aspects and Mathematical Formulation of the Problem of a Computerized Aircraft Structural Analysis System 650055
The need for a comprehensive computing system for aircraft structural analysis is discussed. Suitable criteria for such a system are presented. The Douglas Redundant Force Analysis, a general purpose digital computer method for static stress analysis, is described. Details of the method are presented, including the structure cutter routine for the automatic selection of redundants. Nonlinear and dynamic applications are considered.
The FORMAT system described is a comprehensive computing approach that permits rapid programming by the engineer of matrix and pseudo matrix operations. The system provides a means for developing and extending structural analytical programs and for combining such programs with dynamic, aerodynamic, and thermodynamic programs in the solution of structural problems.
