Computational modeling of rubber multiaxial pressing applied to ceramic materials
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 07/04/2021)Uniaxial and isostatic powder pressing are well known processes. However, disadvantages such as the production of heterogeneous parts or low productivity, respectively, are intrinsic drawbacks. Rubber Multiaxial Pressing ... -
Desenvolvimento de um ensaio mecânico não convencional para a análise da relaxação de tensões do politetrafluoretileno
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 08/04/2016)The mechanical behavior of materials usually depends on room temperature and loading rate. The identification of the time-dependent mechanical behavior is a great difficulty for the industry in the application of new ... -
Analysis of crack propagation in the wedge splitting test via digital image correlation and finite element analyses
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 19/02/2019)Castable refractories are applied in dangerous environments in which it is unpractical to avoid crack initiation. Therefore, their microstructure is usually complex in order to hinder crack propagation by toughening ... -
Identificação de um modelo viscoelástico para o comportamento de relaxação de tensões do PTFE sob compressão e em temperatura ambiente
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 29/08/2019)The identification of viscoelastic models is important for the design of polymeric parts by making the mechanical behavior of the material predictable under critical conditions. However, the characterization of this behavior ... -
Crack network monitoring upon curing and drying of high-alumina MgO-containing refractory castable via digital image correlation
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 23/12/2020)MgO particles are added to high-alumina refractory castable formulations to form spinel at high temperatures. However, these particles react with water forming brucite, which causes heterogeneous expansions in the material ... -
On the thermomechanical behavior of model composites using digital image correlation
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 28/07/2024)In composite systems with incompatibility between the coefficients of thermal expansion (CTE) of their phases, stresses can lead to cracking of the material during a temperature variation. Analytical, numerical and ...
