Free tools and strategies for the generation of 3D finite element meshes: Modeling of the cardiac structures
(2013-06-11)
The Finite Element Method is a well-known technique, being extensively applied in different areas. Studies using the Finite Element Method (FEM) are targeted to improve cardiac ablation procedures. For such simulations, ...
Finite-Dimensional Pointed Hopf Algebras Over Finite Simple Groups of Lie Type IV: Unipotent Classes in Chevalley and Steinberg Groups
(Springer, 2020-06-14)
We show that all unipotent classes in finite simple Chevalley or Steinberg groups, different from PSLn(q) and PSp2n(q), collapse (i.e. are never the support of a finite-dimensional Nichols algebra), with a possible exception ...
An Eulerian finite element with finite rotations for thin-walled composite beams.
(Asociación Argentina de Mecánica Computacional, 2010-11)
An Eulerian beam finite element for composite thin-walled beams considering arbitrary displacements and rotations is presented. As a distinct feature, the virtual work equations are written as a function of generalized ...
SECOND-ORDER FINITE DIFFERENCE APPROXIMATIONS OF THE UPPER-CONVECTED TIME DERIVATIVE\ast
(Siam Publications, 2021-01-01)
In this work, new finite difference schemes are presented for dealing with the upper convected time derivative in the context of the generalized Lie derivative. The upper-convected time derivative, which is usually encountered ...
A mixture theory based method for three-dimensional modeling of reinforced concrete members with embedded crack finite elements
(Techno-Press, 2008-12)
The paper presents a methodology to model three-dimensional reinforced concrete members by means of embedded discontinuity elements based on the Continuum Strong Discontinuous Approach (CSDA). Mixture theory concepts are ...
A cellular automaton-finite difference simulation of the ausferritic transformation in ductile iron
(Maney Publishing, 2018-09-22)
The development of the ausferritic transformation of a ductile iron was analysed using a novel cellular automaton-finite difference model, which considers geometrical details of the microstructure, nucleation of the new ...
