Structural topology optimization for crashworthiness

International Journal of Crashworthiness, 2004
Abstract This paper presents a method to obtain optimum topologies of structures subject to impact loads that produce geometric and material nonlinear behavior, surface contact, friction, and other phenomena in shell and three-dimensional structures. The main feature of this method is an algorithm that does not use sensitivity (gradient) information ...

Evolutionary and GPU computing for topology optimization of structures

Swarm and Evolutionary Computation, 2017
Abstract Although structural topology optimization, as a discrete optimization problem, has been successfully solved several times in the literature using evolutionary algorithms (EAs), the two key difficulties lie in generating geometrically feasible structures and handling a high computation time. These two challenges are addressed in this paper by

Shape and Topology Optimization of Structures

1995
Structural optimization links conventional analysis tools to mathematical optimization schemes (Figure 1). The parameterization of the geometry plays an important role reducing the number of optimization variables [3] (Figure 2). The present study focuses on two aspects: The extension of conventional shape optimization to geometrically nonlinear and ...

Topology Optimization of Discrete Structures

1997
We discuss standard problems of topology optimization of discrete structures. This paper is an attempt to provide an (almost) self-contained introduction and stresses the techniques of reformulating problems and mathematical tools needed for a successful numerical treatment.

Topology optimization of periodic structures

This thesis investigates topology optimization techniques for periodic continuum structures at the macroscopic level. Periodic structures are increasingly used in the design of structural systems and sub-systems of buildings, vehicles, aircrafts, etc.
