Optimization of trusses using genetic algorithms for discrete and continuous variables

M.R. Ghasemi, E. Hinton, R.D. Wood

This paper demonstrates the use of genetic algorithms (GAs) for size optimization of trusses. The concept of rebirthing is shown to be considerably effective for problems…

A design algorithm for the optimization of laminated composite structures

Roberto Spallino, Giuseppe Giambanco, Santi Rizzo

This paper is devoted to the optimal design of laminated composite structures. The goal of the study is to assess the quality and the performance of an algorithm based on the…

Development of a grid‐based mesh generation technique and its application to remeshing during the finite element simulation of a metal forming process

Y.K. Lee, D.Y. Yang

An easy and robust grid‐based approach is proposed to construct the fully hexahedral mesh in three‐dimensional case and its application for the mesh regeneration or remeshing…

Approximate inverse banded matrix techniques

George A. Gravvanis

A new class of approximate inverse banded matrix techniques based on the concept of LU‐type factorization procedures is introduced for computing explicitly approximate inverses…

Comparative investigation into the dynamic explicit and the static implicit method for springback of sheet metal stamping

S.W. Lee, J.W. Yoon, D.Y. Yang

Two kinds of time integration methods; the dynamic explicit method and the static implicit method, have been compared, especially with emphasis on the shell formulations and the…

Implicit dynamic analysis of VE‐damped structures using Maxwell parallel systems

Alessandra Aprile, Andrea Benedetti

A direct integration method for the dynamic analysis of structures equipped with viscoelastic dampers (VED) is presented in this paper. The constitutive model of the damper is set…
