Abstract
Porous structural design has attracted tremendous interest because of the advances in additive manufacturing and the superior characteristics of porous structures. This study presents a filter approach for porous structural design in the framework of single-scale density-based topology optimization. It in principle follows the idea to control porosity by limiting the local volume fraction of material.These local limits are usually incorporated into the optimization problem as a number of individual constraints or one condensed constraint. In contrast to the conventional constraint approach, a filter approach is proposed here to explicitly integrate these local limits into the material interpolation and have them automatically satisfied during the optimization iterations. A variety of numerical examples have been studied to validate the effectiveness of the filter approach.
