Resumo: | Concrete is a composite material widely used in the construction industry. Allied to steel reinforcement, it has mechanical characteristics favorable to use in the most diverse structural elements such as foundations, beams, slabs, columns and dams, for example. Despite its wide use, the material response to extreme situations - such as high temperatures - is quite complex since, in these cases, microstructural changes occur that impact its macroscopic properties. In this context, the use of computational tools that allow the simulation of different structures and loading situations is an interesting strategy for verifying the performance of the material in each scenario. Therefore, this work intends to simulate the mechanical behavior of concrete considering situations of usual stress as well as situations of thermal stress, with the objective of evaluating the impact of the latter on the material. For this, Python scripts are used to generate the geometry, finite element software is used in pre- and post-processing and a user subroutine, developed in Fortran and which describes the Mazars damage model, is used together with said software in the processing phase. |

Aliado à armadura de aço, apresenta características mecânicas favoráveis ao emprego nos mais diversos elementos estruturais tais como fundações, vigas, lajes, pilares e barragens, por exemplo. Apesar de sua ampla utilização, a resposta do material diante de situações extremas - como sob temperaturas elevadas - é bastante complexa uma vez que, nestes casos, ocorrem alterações microestruturais que impactam em suas propriedades macroscópicas. Neste contexto, o emprego de ferramentas computacionais que permitam a simulação de diferentes estruturas e situações de carregamento é uma estratégia interessante para a verificação do desempenho do material em cada cenário. Sendo assim, este trabalho pretende simular o comportamento mecânico do concreto considerando situações de solicitação usual bem como situações de solicitação térmica, com o objetivo de avaliar o impacto desta última sobre o material. Para isso, scripts Python são utilizados para a geração da geometria, um software de elementos finitos é empregado no pré e no pós-processamento e uma subrotina de usuário, desenvolvida em Fortran e que descreve o modelo de dano de Mazars, é utilizada em conjunto com o referido software na fase de processamento.Universidade Federal de Viçosa - UFV2023-01-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo, Manuscrito, Eventosapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1521510.18540/jcecvl9iss1pp15215-01aThe Journal of Engineering and Exact Sciences; Vol. 9 No. 1 (2023); 15215-01aThe Journal of Engineering and Exact Sciences; Vol. 9 Núm. 1 (2023); 15215-01aThe Journal of Engineering and Exact Sciences; v. 9 n. 1 (2023); 15215-01a2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/15215/7742Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAssis, Lahis Souza deBastos, Flávia de SouzaFarage, Michèle Cristina ResendeBarros, Giovanna Tavares de2023-02-24T18:44:16Zoai:ojs.periodicos.ufv.br:article/15215Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2023-02-24T18:44:16The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false |
