Abstract: Competition is introduced among the populations of a number of genetic algorithms (GAs) in solving optimization problems. The aim is to adapt the parameters of the GAs, by altering the resources of the system, so as to ...

Abstract: In this work, the particle swarm optimization method is employed for the reliability-based optimal design of statically determinate truss structures. Particle swarm optimization is inspired by the social behavior of flocks ...

Abstract: A hysteretic plate finite element for inelastic, static and dynamic analysis is presented and its performance is compared with currently used methods. A smooth, 3D hysteretic rate-independent model is utilized generalizing ...

Abstract: A method is presented, employing Flügge and Donnel type theories, for obtaining the dynamic characteristics of cylindrical panels of noncircular cross section, having simply supported curved edges and any boundary conditions ...

Abstract: A hysteretic shell finite element for the nonlinear, static, and dynamic analysis of structures is presented, formulated on the basis of classical theory of plasticity and finite deformation. The generalized smooth, ...

Abstract: In this work, a plane-stress element is proposed for the elastoplastic dynamic analysis of two-dimensional structures exhibiting hysteretic behavior. The constant-strain triangular element formulation for the elastic case ...

Abstract: A smooth hysteretic formulation for modeling of damage is presented, emanating from damage mechanics and classical theory of plasticity. This generalized smooth, rate-independent three-dimensional (3D) Bouc–Wen type model ...
