The results of numerical simulation of the deformation behavior of gyroid gradient structures under different types of loading are presented. The influence of structural parameters and gradient properties on the mechanical behavior has been studied. © 2022 The Authors. Published by ELSEVIER B.V.

Introduction Issues of relationship between the structure and properties of materials are often addressed as a part of the problems of modern materials science. On a sufficiently small scale, all natural and synthetic materials are heterogeneous - they represent either composition of different materials, as, for example, composites, or the same material in different configurations, as polycrystals (Bargmann et al., 2018; Tashkinov, 2021). One of the promising concepts for creating materials with tailored response is design of structurally heterogeneous materials with a gradient of properties. In recent years, the use of porous 3D-printed functionally graded materials (FGMs) has increased significantly (Panesar et al., 2018). An important aspect of gradient structures is the smoothing of the stress fields for elimination of concentrators caused by abrupt geometric changes. One of the rapidly developing application fields for FGMs is ICSI 2021 The 4th International Conference on Structural Integrity Numerical simulation of deformation behavior of additively manufactured polymer lattice structures with a porosity gradient Nataliya Elenskaya a , Mikhail Tashkinov a* a Perm National Research Polytechnic University, Komsomoslky Ave. 29, Perm 614990, Russia Abstract This study devoted to investigation of the mechanical behavior of three-dimensional gradient open-cell porous structures which geometry is based on triply periodic minimal surfaces.
