Computerized Analysis of Non-Isotropic Structures,
Abstract
A structural analysis method accommodating the effects of non-isotropic materials is presented. The structure is idealized as an assembly of bar and plate elements. Stresses and deflections are computed using a computerized solution procedure based on the matrix displacement approach. The element stiffness matrices are obtained by use of an orthotropic stress-strain relationship which is derived from the generalized Hooke's law. Data input consists of Young's moduli, Poisson's ratios, a shear modulus, and the thermal coefficients. The program computes displacements at each node, the stresses for each plate element, and the reactions at fixed nodes. Application of this procedure to a typical composite structure is described, including correlation between analysis and test data. (Author)
