Topology Optimization

Educational article Struct Multidisc Optim 21, 120127 ? Springer-Verlag 2001 A 99 line topographic anatomy optimisation engrave indite in Matlab O. Sigmund Abstract The piece presents a compact Matlab carrying into action of a topographic anatomy optimisation jurisprudence for compliance minimisation of statically sended structures. The total numerate of Matlab arousal lines is 99 including optimizer and Finite subdivision subroutine. The 99 lines argon shared into 36 lines for the main broadcast, 12 lines for the Optimality Criteria based optimizer, 16 lines for a meshindependency ?lter and 35 lines for the ?nite segment computer code. In fact, excluding comment lines and lines associated with make and ?nite element analysis, it is shown that only 49 Matlab scuttlebutt lines are necessitate for firmness of purpose a well-posed analysis situs optimisation problem. By adding trine redundant lines, the political platform can sack problems with sevenfold load cases. The code is intend for educational purposes. The consummate(a) Matlab code is accustomed in the Appendix and can be down-loaded from the web-site http://www.topopt.dtu.dk. line words network topology optimization, education, optimumity criteria, world-wide web, Matlab code 1 Introduction The Matlab code presented in this paper is intended for engineering education.

Students and newcomers to the ?eld of topology optimization can down-load the code from the web-page http://www.topopt.dtu.dk. The code may be uptaked in courses in geomorphological optimization where students may be assigned to do extensions such as multiple load-cases, choice mesh-independency schemes, passive areas, etc. some other possibility is to use the program to develop students intuition for optimum design. Advanced students may be asked to guess the optimal topology for given leaping characterize and volume Received October 22, 1999 O.
