Design and mechanical performances of stress adaptive porous structures based on triply period minimal surface

In this study, a design method is proposed for the stress adaptive porous structures with triply period minimal surface (TPMS). The method depends upon the modeling method of solving porous structures with complex contour and the mapping method achieved by mapping functions of mechanical properties for TPMS based porous structures. Additionally, the implementation framework is provided, and the proposed modeling method is evaluated by an example. The results show that the stress adaptive structures possess higher stiffness and peak stress, compared with uniform or graded type, which proved the promising potential in engineer applications, bone implants and efficient heat exchanger.
