Topology Optimisation of A Two Point Load case Continuum Structure using Firefly Algorithm - IV

Abstract

Topology optimization is a relatively new and emerging area of research in the field of structural engineering. The idea is to determine the optimum distribution of material in the given design domain and not to focus on shape orcorrecting the dimensions of initial designs. Metaheuristics are widely used in the field of optimization of continuum structures. Firefly algorithm proposed by Xin-She Yang is considered as one of the best performing algorithms which require less iteration to converge. This paper is a series of ongoing research work in structural optimization using firefly algorithm. The focus of this paper is to optimize atwo point load case problem one of the complex in the field of optimization involving several degrees of freedom. Anattempt has been made to verify the distribution of material and the convergence of the firefly algorithm. The analysis shows that the algorithm is very effective to determine the distribution of material and the final distribution is a near approximation of the theoretical distribution.
