NUMERICAL ANALYSIS OF DEFORMATION UNDER COMPRESSION OF STRUCTURES BASED ON TRIPLY PERIODIC MINIMAL SURFACES

Complex porous structures based on triply periodic minimal surfaces with high values of specific physical and mechanical characteristics are increasingly used in many industries. Numerical analysis is of great importance in evaluating the load-carrying capacity and mechanical behavior of such structures. The paper presents the results of finite element analysis of the stress-strained state of structures composed of triply periodic minimal surfaces and affected by compressive loading. The complexity of simulating the response of such structures to mechanical effects lies in the large dimension of the problem due to the need for fine discretization required for an adequate representation of the complex geometry of the model. The stages of constructing facet geometry for the construction of numerical models are shown. The effect of the type and parameters of these structures on their mechanical behavior under compression is exemplified by Schoen IWP surfaces and Schwarz primitives. Stiffness efficiency depending on the structure topology is analyzed.
