The multi-material topology optimization (MMTOP) is established to evaluate the behaviour of many materials in a problem and give an applicable solution for design. In this study, we present a polytree-based adaptive methodology for multi-material topology optimization (MMTOP). Polytree data ...

Multi-material topology optimization has also been used in a phase field setting [20] and from an optimal control point of view [21]. Moreover, the approach introduced in [14] has been extended to the multi-material case, e.g., in [22]. In this work, we propose an alternative way ...
A heuristic approach to handle strength constraints based on material failure criteria in multi-material topology optimization is presented. This is particularly advantageous if different materials have different failure criteria. The change in the material failure function in an element due to a contempla...

By employing an alternating active-phase algorithm of the Gauss-Seidel version, the multi-material topology optimization problem is split into a series of binary topology optimization sub-problems, which can be easily solved using the modified SIMP model. Several 2D examples are presented to ...
