Numerical solution of some boundary value problems in nonlinear magneto-elasticity
(Sage, 2015)
In the context of the theory of nonlinear magneto-elastic deformations, the problem of the extension (shortening) of a
cylinder of finite length under the influence of a magnetic field applied far away in free space is ...
Analytical model of the temperature distribution in the cutting tool for orthogonal cutting process
(Joinville, SC, 2022-03-14)
This work presents an analytical model of the tool temperature distribution field for the cutting process with a new geometrical boundary assumption regarding the current models in the literature. Most of the mechanical ...
A Stokes-residual backflow stabilization method applied tophysiological flows
(Elsevier, 2016-05)
In computational fluid dynamics, the presence of incoming flow at open boundaries (backflow) might often yield unphysical oscillations and instabilities issues, even for moderate Reynolds numbers. It is widely accepted ...
Laplace Form Of Navier-Stokes Equations: A Safe Path Or A Wrong Way?
(Asociacion Argentina de Mecanica Computacional, 2006-11)
The Navier-Stokes Equations written in Laplace form are often the departure point for the simulation of viscous newtonian flows and some studies of numerical stability. Researchers may not be fully aware that the “physical ...
A basic convergence result for conforming adaptive finite element methods
(World Scientific, 2008-05)
We consider the approximate solution with adaptive finite elements of a class of linear boundary value problems, which includes problems of "saddle point" type. For the adaptive algorithm we assume the following framework: ...
Perturbative finiteness of superstring theory
(2004-01-01)
In these proceedings, the multiloop amplitude prescription using the super-Poincaré invariant pure spinor formalism for the superstring is reviewed. Unlike the RNS prescription, there is no sum over spin structures and ...
A critical reassessment of elastic unloading in sharp instrumented indentation experiments and the extraction of mechanical properties
(TAYLOR & FRANCIS LTD, 2011)
This work examines the extraction of mechanical properties from instrumented indentation P-h(s) curves via extensive three-dimensional finite element analyses for pyramidal tips in a wide range of solids under frictional ...
A hybrid-mixed method for elasticity
(Edp Sciences S A, 2016-04)
This work presents a family of stable finite element methods for two-and three-dimensional linear elasticity models. The weak form posed on the skeleton of the partition is a byproduct of the primal hybridization of the ...
New mixed finite element methods for natural convection with phase-change in porous media
(2019)
This article is concerned with the mathematical and numerical analysis of a steady phase change problem for non-isothermal incompressible viscous flow. The system is formulated in terms of pseudostress, strain rate and ...
