Abstract
The aim of this work is to investigate the influence of the shape of voids in porous 3D printed closed-cell porous structures on their elastic properties and mechanical behavior using the results of morphological analysis of microstructure based on multipoint statistical characterization, finite element modelling and experimental data. The geometrical models of representative volume elements (RVEs) for structures with non-overlapping inclusions of different shapes and parameters were created and produced using FDM/FFF 3D printing technology. Evaluation of various morphological parameters has been performed based on the analysis of multipoint statistical characteristics. The elastic behavior and properties of the studied RVEs were modelled using finite element analysis. The relationship between mechanical properties and statistical characteristics has been analyzed.
