Computer program for directed structure topology optimization

摘要: To compensate for the imperfection of traditional bi-directional evolutionary structural optimization, material interpolation scheme and sensitivity filter functions are introduced. A suitable can overcome checkerboard mesh-dependency. And historical information on accurate elemental numbers used to keep objective function converging steadily. Apart from rational intervals relevant important parameters, concept distinguishing between active non-active elements design is proposed, which be widely improving artistry structures directly, especially a one whose size not given. Furthermore, user-friendly software packages developed enhance its accessibility practicing engineers architects. reduce time cost large time-consuming complex structure parallel computing built-in in MATLAB codes. The program easy use who may familiar with either FEA or optimization. developers make deep research algorithm by changing Several classical examples given show that improved BESO method superior handy utility computer software.
