Digital Computer Program for the Analysis of Aerospace Structures by the Matrix Displacement Method

摘要

This report presents a detailed development of the Matrix Displacement Method and describes an available computer program which can be used for the stress and deflection analysis of arbitrary structures idealized into an assembly of axial load members (bars), triangular panels, rectangular panels with linearly varying edge displacements, and rectangular panels with an assumed (Turner) stress distribution. Only the translational degrees of freedom are considered in this program. Five different loading conditions may be analyzed simultaneously, and for each condition a separate temperature distribution may be specified. A description of the digital analysis, instructions for the use of the available program, and an illustrative analysis problem are presented. (Author)
