Verificação teórico-numérico de modelo constitutivo aplicado a fluidos tixotrópicos compostos por duas estruturas distintas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEngenharia MecânicaUTFPR, 2017-11-14)
The application of thixotropic fluids in several industrial sectors such as chemical, food and petroleum are examples of the motivation to seek the understanding of thixotropic fluid behavior. Two equations are usually ...
Austempering heat treatment of ductile iron: Computational simulation and experimental validation
(Elsevier Science, 2017-10)
The three-step austempering heat treatment of ductile iron parts in this paper is simulated by employing a coupled thermo-mechanical-metallurgical model. The thermo-mechanical formulation is solved in the macroscale using ...
Thermo-mecano-metallurgical modelling of welding: application to welded joints in nuclear power plants
(2014-11-17)
The Thermo-Mecano-Metallurgical modelling of welding is considered in this thesis, where the high non-linearity and the multiphysics character of the problem makes necessary to study different areas of Computational ...
Internal carburisation of an industrial alloy: a quantum chemical study of microstructure's changes
(Taylor & Francis, 2013-08)
A quantum chemical theoretical study on the chemical bonding and electronic structure of the γ-FeNiCr–C interaction is performed using the Atom Superposition and Electron Delocalisation method in order to contribute to the ...
Design of the austempering heat treatment of a ductile iron differential case aided by computer simulation
(Latin Amer J Solids Structures, 2018-06)
Austempered ductile iron is frequently employed in the fabrication of automobile parts due to its good mechanical properties, and its simplicity and low cost of the manufacturing process. The heat treatment design is an ...
Experimental validation of computational models for mass transport through micro heterogeneous membranes
(Elsevier Science, 2013-02-27)
This work describes a setup for the experimental and theoretical study of the mass transport of a penetrant through a two-dimensional model-material microstructure consisting in a homogeneous matrix with slender obstacles. ...
Cohesive surface model for fracture based on a two-scale formulation: computational implementation aspects
(Springer, 2016-10)
The paper describes the computational aspects and numerical implementation of a two-scale cohesive surface methodology developed for analyzing fracture in heterogeneous materials with complex micro-structures. This approach ...
