Uma nova abordagem para análise estática em duas escalas : método dos elementos finitos generalizados/estendidos, estratégia global-local e modelos de degradação elástica no estudo de meios não lineares, parcialmente frágeis e heterogêneos
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ESTRUTURASPrograma de Pós-Graduação em Engenharia de EstruturasUFMG, 2021-01-20)
In structural analysis it is usual to adopt single-scale models, representing the structural or macroscopic level, in which one would investigate the overall behaviour of the studied domain. In those models, the material ...
Tratamento de descontinuidade de material no método dos elementos finitos generalizado
(Universidade Federal de Minas GeraisUFMG, 2012-10-05)
The study of Non-Conventional Element Method Formulations is based on alternative approaches to the Finite Element Method including the Meshless Methods and the Generalized Finite Element Method. The Generalized Finite ...
Crack propagation modeling in plane structures using two-scale generalized/extended finite element method
(Universidade Federal de Minas GeraisUFMG, 2017-08-07)
Finite Element Method (FEM) has been widely used for the numerical modeling of structural/mechanical problems. Use of computer-based FEM programs was greatly facilitated with the development of pre- and post-processors ...
