Abstract
The “Bubble Method” is one of the methods of topology optimization techniques. Its basic idea is to iteratively position new holes (bubbles) in a structure by means of a definite function and a hierachically secondary shape optimization. The expression of the definite function depends on the special optimization functionals and the material behaviour. In this paper the difference of optimal shapes of a cantilever disc made of ductile and brittle materials is presented and, furthermore, the Bubble Method is used for finding a best possible initial design of a cantilever disc made of ductile materials.
