A loading rate dependent cohesive model for concrete fracture
(Pergamon-elsevier Science LtdOxfordInglaterra, 2012)
Study of a stabilized mixed finite element with emphasis on its numerical performance for strain localization problems
(John Wiley & Sons Ltd, 2008-12)
The numerical performance of a stabilized mixed finite-element formulation based on the pressuregradient- projection method (PGP) using equal-order (linear) interpolation is evaluated by solving solid mechanics problems, ...
Discontinuous bifurcation analysis of thermodynamically consistent gradient poroplastic materials
(Elsevier, 2014-02)
In this work, analytical and numerical solutions of the condition for discontinuous bifurcation of thermodynamically consistent gradient-based poroplastic materials are obtained and evaluated. The main aim is the analysis ...
A generalized finite-strain damage model for quasi‐incompressible hyperelasticity using hybrid formulation
(John Wiley & Sons Ltd, 2016-03)
A new generalized damage model for quasi-incompressible hyperelasticity in a total Lagrangian finite-strain framework is presented. A Kachanov-like reduction factor (1 - D) is applied on the deviatoric part of the hyperelastic ...
Comportamento mecânico do aço AISI 41B30 na deformação a quente
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de Minas - Mestrado ProfissionalUFMG, 2021-05-28)
High pressure gas cylinders (gas cylinders) are manufactured from the rolling of special seamless steel tubes. The efforts required during the rolling step are directly dependent on the chemical composition of steels, ...
Enfoque variacional a la homogenización de una barra heterogénea en fase post-crítica
(2018)
In the present work we seek to explore concepts related to the one-dimensional fracture using variational homogenization as a conceptual framework for analysis. The variational approach opens the possibility of analyzing ...
Estudo do comportamento mecânico das ligas de titânio beta metaestável TMZF e Ti15%Mo durante processamento termomecânico
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2020-10-02)
Stress-strain curves of two metastable beta titanium alloys, the Ti-15%Mo alloy and the TMZF alloy were evaluated. The curves were obtained from isothermal hot compression tests in a temperature range from 650 to 900 ° C, ...
