Design Sensitivity Analysis of Dynamics of Built-Up Structures Using Ritz and Mode Acceleration Meth the minimal eigenbasis. The continuum-based DSA methods can be implemented outside established finite element analysis (FEA) codes by post-processing analysis data, and it does not require information on the stiffness, damping, and mass matrices and their derivatives. Moreover the method is efficie

Method of Error Elimination for a Class of Semi-Analytical Sensitivity Analysis Problemshat problem dependent, exact error analysis is not required, and that it both eliminates the dependence of the error of the sensitivity on finite element mesh refinement and on design variable pertubation. Also, the method is computationally inexpensive because the differentation of the stiffness co

Modern computer technology enables us to analyse systems with many thousand degrees of freedom. In the optimization of structural systems, however, most currently av

Iterative COC Methodsor a variety of design constraints. For trusses with stress constraints and a deflection constraint an independent derivation of the optimality criteria is presented and then the method is illustrated by an example involving a ten-bar truss. A detailed comparison with the DOC approach is given and s
