Functionally graded porous structures: Analyses, performances, and applications – A Review

Abstract

Structural innovation incorporating bio-inspired composites poses a fresh angle to develop novel lightweight forms with strengthened mechanical properties, among which a must-discuss topic is porous structures. The introduction of internal pores mimics the natural bones or timbers, makes the density a designable parameter, and opens a new world for researchers and engineers who have been obsessed in a variety of porous structural forms with desired aspects. One of the important trends is the development of functionally graded (FG) porous structures, where internal porosity gradations present significant potential to further enhance the already superior performances. This paper is aimed to re..
