โœฆ Synopsis

The algorithm optimization presented uses the optimality criteria method so as to minimize the total weight of the structure in the presence of a constraint of the damping type. The goal of this study is to increase the structural damping by optimizing the viscoelastic and elastic material distribution over the structure. The types of damping considered are hysteristic. The gradient of the constraint function in relation to the design variables is calculated with the aid of a complex variable sensitivity method. Several numerical results are presented to validate the algorithm proposed.

This paper presents a method for considering fatigue life requirements in the optimal design of structures. The basic concept is to use the load history data combined with the finite element stresses of the structure and the material fatigue properties to calculate the fatigue life during the optim

## Abstract This paper presents an optimization method based on optimality criterion for minimum weight of structures with stability requirements. A recurrence relation is derived and the method is explained in the context of the displacement method of finite element analysis. The incipient bucklin
