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

DOI: 10.17804/2410-9908.2024.4.047-056

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.

Keywords: triply periodic minimal surfaces, finite element model, Schwarz primitive, Schoen IWP, stress-strain state

ЧИСЛЕННЫЙ АНАЛИЗ ДЕФОРМИРОВАНИЯ ПРИ СЖАТИИ СТРУКТУР НА ОСНОВЕ ТРИЖДЫ ПЕРИОДИЧЕСКИХ МИНИМАЛЬНЫХ ПОВЕРХНОСТЕЙ

Сложные пористые структуры, основанные на трижды периодических минимальных поверхностях, обладающие высокими удельными показателями физико-механических характеристик, находят все более широкое применение во многих отраслях промышленности. Численный анализ имеет большое значение при оценке несущей способности и механического поведения таких структур. В работе представлены результаты конечно-элементного анализа напряженно-деформированного состояния структур, составленных из трижды периодических минимальных поверхностей, под действием сжимающей нагрузки. Сложность моделирования отклика таких структур на механическое воздействие заключается в большой размерности задачи, обусловленной необходимостью мелкой дискретизации, требуемой для адекватного представления сложной геометрии модели. Показаны этапы построения фасетной геометрии для формирования численных моделей. На примере поверхностей Шёна IWP и примитивов Шварца рассмотрено влияние типа и параметров данных структур на их механическое поведение при сжатии. Выполнен анализ жесткостной эффективности в зависимости от топологии структур.

Ключевые слова: трижды периодические минимальные поверхности, конечно-элементная модель, примитивы Шварца, поверхности Шёна, напряженно-деформированное состояние
