Abstract

In continuum structural topology optimization

Genetic Algorithm (GA) was served as optimization method

binary chromosome of GA was employed to represent a topology structure

and finite element method was used to obtain the displacement

stress and strain of each node

which was included in constraint conditions.In order to improve the efficiency and to make the optimization results better

the simulated annealing technique was embedded with genetic algorithm.The method could adjust the function during optimization.A cantilever plate

as an example

was optimized to show the efficiency of the method.
