Determination of the numerical parameters of a continuous damage model for the structural analysis of clay brick masonry
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2012-12-01)
Models based on the continuous damage theory present good responses in representing the nonlinear behavior of reinforced concrete structures with loss of strength and stiffness of the material. However, damage theory is ...
Nonlinear dynamic numerical analysis of a RC frame subjected to seismic loading
(Elsevier, 2017-05)
In the context of seismic engineering, reliable modeling methodologies are needed to represent the nonlinear dynamic behavior of structures under the effect of the seismic action. Only in this way is it possible to assess ...
Numerical analysis of fibre reinforced polymer retrofitted masonry panels
(Elsevier, 2012-12)
The numerical analysis of the in-plane mechanical behaviour of unreinforced and carbon fibre reinforced polymer (CFRP) retrofitted masonry walls, using a coupled damaged-plasticity model, is presented in this paper. The ...
Precisão de plantas planialtimétricas em função do posicionamento de pontos em irradiadas de campo
(2006-01-01)
The present experiment aimed to study the influence of point positioning in an irradiated field to produce a planialtimetric plant. A planialtimetric evaluation was carried out in a 14-acre experimental area with well-defined ...
Numerical modeling of flow through an industrial burner orifice
(Elsevier B.V., 2014-06-01)
This paper presents numerical modeling of a turbulent natural gas flow through a non-premixed industrial burner of a slab reheating furnace. The furnace is equipped with diffusion side swirl burners capable of utilizing ...
Three-dimensional transient complex free surface flows: Numerical simulation of XPP fluid
(2013-05-01)
In this paper we present a finite difference MAC-type approach for solving three-dimensional viscoelastic incompressible free surface flows governed by the eXtended Pom-Pom (XPP) model, considering a wide range of parameters. ...
Recursive computation of matrix elements in the numerical renormalization group
(Elsevier BVAmsterdam, 2014-04)
The numerical renormalization group is an efficient method to diagonalize model Hamiltonians describing correlated orbitals coupled to conduction states. While only the resulting eigenvalues are needed to calculate the ...
Numerical solution and validation concerning a descriptive model of a simultaneous heat and mass transfer process
(Praise Worthy Prize, 2011-07)
This paper deals with the numerical solution of an initial moving boundary problem (IMBVP) arising from a simplified version of a free boundary problem (IFBVP) which was formulated in another paper, as a mathematical model ...
A steady-state model for heat pipes of circular or rectangular cross-sections
(1996-08-01)
The objective of this paper is to present a generalized analytical-numerical model of the internal flow in heat pipes. The model formulation is based on two-dimensional formulation of the energy and momentum equations in ...
