Abstract
The use of multiple-material topological optimization in the design and modeling of structural components is considered. As an example, the topological optimization of an L-shaped bracket is studied. The beam is first optimized with the option of using two materials of different elastic modulus—for example, titanium and steel. Optimization is also used to determine the zone occupied by cellular structure in the component. In this case, part of the component consists of continuous material; and the remainder consists of cells whose effective properties are known in advance. The results of optimization are outlined in both cases. The applicability of these approaches is assessed.
