Journal ArticleDOI
Simplified calculation of eigenvector derivatives
TL;DR: A simplified procedure is presented for the determination of the derivatives of eigenvectors of nth order algebraic eigensystems, applicable to symmetric or nonsymmetric systems, and requires knowledge of only one eigenvalue and its associated right and left eigenavectors.
Journal ArticleDOI
Modelling the elastic behaviour of granular materials
Poul V. Lade,Richard B. Nelson +1 more
TL;DR: In this article, a nonlinear, isotropic model for the elastic behavior of granular materials is developed on the basis of theoretical considerations involving the principle of conservation of energy.
Journal ArticleDOI
Nonassociated Flow and Stability of Granular Materials
TL;DR: In this paper, a series of triaxial tests designed to expose the type of behavior displayed by granular materials are presented and discussed, and reliability of the test results, the possible influence of viscous effects on the stability, and the effect of release of elastic energy are studied and discussed in detail.
Journal ArticleDOI
Instability of granular materials with nonassociated flow
TL;DR: In this paper, a series of triaxial tests designed to expose the type of behavior displayed by granular materials are presented and discussed and stability conditions for materials with nonassociated flow are presented.
Journal ArticleDOI
Automated Structural Synthesis Using a Reduced Number of Design Coordinates
TL;DR: In this article, the authors used a deflected gradient procedure to generate a Fiacco-McCormi ck penalty function, which is then minimized with a reduced set of design variables.
