3D printing of a composite structure with shape memory materials requires a special approach to the subject, at the stage of the design and printing process. This paper presents the design steps during the development of a 3D-printed composite structure with shape memory material. The connection points between the SMA fibers and the printer filament are developed in the MATLAB environment. Finite element method is used to simulate the shortening of the shape memory material under the influence of temperature and its effect on the printed polymer material is presented. In the MATLAB environment, evolutionary algorithms were used to determine the shape of the SMA fiber alignment. This work demonstrates the use of shape memory effect in 3D printed smart composite structures, where the component takes a predetermined shape. The structure obtained as a result of such printing changes with the heat generated by the current voltage, making it the desired fourth dimension.

Este estudo tem por objetivo evidenciar a importância do vestuário como um objeto que atinge diretamente a ação da recordação através de três formas distintas: a presença da peça de vestuário; algo que possa representar a peça, como uma fotografia; ou da lembrança da peça, como um retalho de tecido. Para comprovar esta investigação, apropriou-se dos conceitos de autores fundamentais para tanto da área da memória social quanto da cultura material e da moda, que pudessem servir como base para esta comprovação. Sendo esta uma pesquisa que faz parte da fase inicial da dissertação da autora, contou-se como procedimento metodológico para o seu desenvolvimento, a elaboração de uma revisão bibliográfica, servindo como suporte inicial para algumas indagações desta pesquisa, e trazendo em seus resultados parciais as reflexões surgidas sobre os conceitos abordados.Palavras-chave: Vestuário; memória social; cultura material.Abstract This study aims at highlighting the importance of clothing as an object that directly affects the action of remembering through three distinct forms: the presence of the garment; something that can represent the piece, like a photograph; or the memory of the piece, like a scrap of fabric. To prove this investigation, the concepts of fundamental authors were used for both the area of social memory and material culture and fashion, which could serve as a basis for this verification. This being a research that is part of the initial phase of the author's master thesis, a methodological procedure for its development was considered, together with the elaboration of a bibliographic review, serving as initial support for some questions of this research, and bringing in its partial results the reflections on the concepts addressed.Keywords: Clothing; social memory; material culture.

Введение. Представлено лингвистическое исследование типовых свойств концепта memory и концептуальной категории memory. Устанавливается их терминологическое отношение. Приводится описание моделирования типового состава концепта memory в границах анализируемой категории. Цель исследования состоит в описании, моделировании и анализе авторского сознания в комплексе концептов, концептуальных категорий и смыслов, его репрезентирующих. В задачи исследования входит выявление состава содержания и типовых свойств концепта memory как компонента концептуальной категории memory. Материал и методы. Материалом послужили типовые высказывания на русском и английском языках, содержащие морфемы па/ом, мем, mem, а также ассоциаты слова memory/память. Исследование проводится в контексте коммуникативной и антропоцентрической парадигм. Методы исследования представлены концептуальным, психолингвистическим и лингвосемантическим анализом типовых высказываний на русском и английском языках, репрезентирующих состав концепта memory, а также типовые свойства концептуальной категории memory. Результаты и обсуждение. Смоделированы типовое содержание и психолингвистические свойства концепта memory в составе концептуальной категории memory. Вербальная (по корневым морфемам па/ом, мем, mem) и ассоциативная выборка типовых высказываний, репрезентирующих концепт memory, демонстрирует типовое содержание концепта и обозначает его функциональные свойства в составе концептуальной категории memory. Различные речевые варианты реализации концепта memory поддаются описанию как малые варианты репрезентации концепта. Реализация концепта в составе внутреннего содержания обозначения объектов культуры и искусства, а также в составе художественного нарратива создает большие варианты. Рассмотренные и наметившиеся типовые состав и свойства концепта memory позволяют изучать концептуальную категорию memory как одну из базовых категорий, задействованных в формировании сюжетной линии и смыслового содержания художественных произведений. Проведенный анализ показывает, что представляется возможным рассматривать художественное произведение как большой вариант реализации концептуальной категории memory. Introduction. This article presents a linguistic study of the typical properties of the concept memory, provides a detailed description of the concept memory and the conceptual category memory; establishes their terminological relationship. The content of the article provides a description of the modeling of typical components of the concept memory within the analyzed category. The purpose of the study. The purpose of the study is to describe, model and analyze author’s consciousness in a complex of concepts, conceptual categories and meanings that represent it. The objectives of the study include identifying the components of the concept and its typical properties functioning as a component of the conceptual category memory. Material and methods. The study is conducted in the context of a communicative and anthropocentric paradigms. The research methods are represented by conceptual, psycholinguistic and semantic analyses of typical utterances in Russian and English, representing the components of the concept memory, as well as typical properties of the conceptual category memory. The material is represented by typical utterances in Russian and English, containing morphemes “па/ом”, “мем” (in Russian), mem (in English), as well as associates of the word “память” / memory. Results and discussion. The tables and corresponding descriptions simulate the typical content and psycholinguistic properties of the concept memory as part of the conceptual category memory. The verbal (possessing root morphemes “па/ом”, “мем” (in Russian), mem (in English) and associative selection of typical utterances representing the concept memory shows typical content of the concept and denotes its functional properties as part of the conceptual category memory. Various speech variants implementing the concept memory are described as small variants representing the concept. The implementation of the concept as part of the internal content of the designation of objects of culture and art, as well as part of the literary narrative (books texts), creates big variants. The emerging typical components and properties of the concept memory makes it possible to consider the conceptual category memory as one of the basic categories involved in the formation of the storyline and the semantic content of literary narrative. The analysis shows that it is possible to consider a text of a literary work (a book) as a big variant of realization of the conceptual category memory.
