A STUDY OF MATRIX ANALYSIS METHODS FOR INELASTIC STRUCTURES.
Abstract
Matrix methods of structural analysis for structures exhibiting elastic-plastic and creep behaviors are reviewed. To elucidate the matrix methods, two problems in plane stress, a bending problem and a shear-lag problem, are chosen as examples. Both are analyzed by model matrix analysis programs, for elastic-plastic behavior by the displacement method and by the force method and for elastic-plastic-creep behavior by the displacement method. A continuous elastic analysis of the shear-lag problem is described and a formulation, for this problem, of a continuous analysis for creep is presented. Experiments conducted on aluminun shear-lag specimens at room temperature for elasticplastic behavior and at an elevated temperature for elastic-plastic-creep behavior are described. The results of the analyses and experiments are compared. A critical discussion of matrix analysis methods for inelastic structures concludes the report. (Author)
