An Adaptive Multiscale Finite Element Method [PDF]
Multiscale Modeling & Simulation, 2014 This work is devoted to an adaptive multiscale finite element method (MsFEM) for solving elliptic problems with rapidly oscillating coeefficients. Starting from a general version of the MsFEM with oversampling, we de- rive an a posteriori estimate for the H1-error between the exact solution of the problem and a corresponding MsFEM approximation.

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Discrete element method to simulate continuous material by using the cohesive beam model [PDF]
, 2012 The mechanical behavior of materials is usually simulated by the continuous mechanics approach. However, simulation of non-continuous phenomena like multi fracturing is not well adapted to a continuous description.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Kriging-Based Finite Element Method: Element-By-Element Kriging Interpolation
Civil Engineering Dimension, 2009 An enhancement of the finite element method with Kriging shape functions (K-FEM) was recently proposed. In this method, the field variables of a boundary value problem are approximated using ‘element-by-element’ piecewise Kriging interpolation (el-KI ...

Acta NumericaCut finite element methods (CutFEM) extend the standard finite element method to unfitted meshes, enabling the accurate resolution of domain boundaries and interfaces without requiring the mesh to conform to them. This approach preserves the key properties and accuracy of the standard method while addressing challenges posed by complex geometries and ...

An Optimal Adaptive Finite Element Method [PDF]
SIAM Journal on Numerical Analysis, 2005 The Dirichlet problem in a polygonal domain \(\Omega\) in \({\mathbb R}^2\) for a second-order elliptic equation with disconinuous coefficients is considered. The finite element methods on triangulations of \(\bar\Omega \) are investigated and the main purpose of the paper is to generalize some published results dealing with convergence analysis of ...
