MULTI-PHASE MATERIAL TOPOLOGY OPTIMISATION METHOD BASED ON ALTERNATIVE SENSITIVITY CALCULATION
JOURNAL OF ENVIRONMENTAL PROTECTION AND ECOLOGY(2019)
Abstract
In order to obtain better multi-phase material topology optimisation results, a multi-phase material topology optimisation method based on alternative sensitivity calculation is proposed. This method decomposes the multi-phase material topology optimisation problem into some two-phase material topology optimisation sub-problems. The solving order of the sub-problems is arranged according to the sum of the calculated sensitivity value of the two-phase material topology optimisation sub-problems, and the multi-phase material topology optimisation problem is solved by alternately solving the two-phase material topology optimisation sub-problems.
