Dual reciprocity boundary element method in Laplace domain applied to anisotropic dynamic crack problems
(Pergamon-elsevier Science LtdOxfordInglaterra, 2003)
The truss‐like discrete element method in fracture and damage mechanics
(Emerald Group Publishing Limited, 2011-12)
Purpose: It is the purpose of this paper to further develop the truss-like discrete element method (DEM) in order to make it suitable to deal with damage and fracture problems. Design/methodology/approach: Finite and ...
Variational modelling of strain localization in solids: a computational mechanics point of view
(2020)
Strain localization is one of the most challenging phenomena in solid mechanics. It occurs when strains concentrate in very narrow bands within a solid, typically referred to as localization bands. This behaviour is related ...
The problem of the classical limit of quantum mechanics and the role of self-induced decoherence
(Springer, 2006-12)
Our account of the problem of the classical limit of quantum mechanics involves two elements. The first one is self-induced decoherence, conceived as a process that depends on the own dynamics of a closed quantum system ...
On some conditionally solvable quantum-mechanical problems
(IOP Publishing, 2020-09-03)
We analyze two conditionally solvable quantum-mechanical models: a one-dimensional sextic oscillator and a perturbed Coulomb problem. Both lead to a three-term recurrence relation for the expansion coefficients. We show ...
A hierarchical consideration of causes and mechanisms of succession
(Kluwer Academic Publishers, 1987)
Questions of successional pattern and causality have been central concerns in vegetation ecology. In this paper we address the limits of the overextended models of Connell and Slatyer by discussing problems encountered in ...
Birkhoffian Systems in Infinite Dimensional Manifolds
(SPRINGER, 2010)
We generalize the theory of Kobayashi and Oliva (On the Birkhoff Approach to Classical Mechanics. Resenhas do Instituto de Matematica e Estatistica da Universidade de Sao Paulo, 2003) to infinite dimensional Banach manifolds ...
Coupled Thermo-Hydro-Mechanical Numerical Modeling of Evolving Fractures in Rocks
(Springer, 2021-04-22)
We present a numerical technique capable of handling evolving fractures in rocks triggered by coupled thermo-hydro-mechanical (THM) phenomena. The approach is formulated in the context of the finite-element method (FEM) ...
SUPG and discontinuity-capturing methods for coupled fluid mechanics and electrochemical transport problems
(Springer, 2013-02)
Electrophoresis is the motion of charged particles relative to the surrounding liquid under the influence of an external electric field. This electrochemical transport process is used in many scientific and technological ...
