Error estimation and h-adaptive refinement in the analysis of natural frequencies
(ELSEVIER SCIENCE BV, 2001-12-01)
This paper deals with the estimation of the discretization error and the definition of an optimum h-adaptive process in the finite element analysis of natural frequencies and modes. Consistent and lumped mass matrices are ...
Analysis of the stability and dispersion for a Riemannian acoustic wave equation
(ELSEVIER SCIENCE INC, 2019-01-15)
The construction of images of the Earth's interior using methods as reverse time migration (RTM) or full wave inversion (FWI) strongly depends on the numerical solution of the wave equation. A mathematical expression of ...
Finite difference schemes for a structured population model in the space of measures
(American Institute of Mathematical Sciences, 2020-01)
We present two finite-difference methods for approximating solutions to a structured population model in the space of non-negative Radon Measures. The first method is a first-order upwind-based scheme and the second is ...
Modelling 3D metal cutting problems with the particle finite element method
(Springer Verlag, 2020-01-01)
This work presents the development of the Particle Finite Element Method (PFEM) for the modelling of 3D solid mechanics problems under cutting conditions. The study and analysis of numerical models reproducing the cut of ...
A finite extensibility nonlinear oscillator
(Elsevier Science Inc, 2011-03)
The dynamics of a finite extensibility nonlinear oscillator (FENO) is studied analytically by means of two different approaches: a generalized decomposition method (GDM) and a linearized harmonic balance procedure (LHB). ...
A mimetic finite difference method using Crank-Nicolson scheme for unsteady diffusion equationA mimetic finite difference method using Crank-Nicolson scheme for unsteady diffusion equation
(Universidad de Costa Rica, Centro de Investigación en Matemática Pura y Aplicada (CIMPA), 2009)
A coupled FEM-SBFEM approach for soil-structure-interaction analysis using non-matching meshes at the near-field far-field interface
(Elsevier, 2019-06)
Nowadays numerical simulation of soil structure interaction (SSI)is applied to different problems, such as the construction of reliable earthquake-resistant structures. To analyze SSI considering unbounded domains, a ...
A survey on finite volume schemes using triangular meshes
