Bayesian Numerical Homogenization [PDF]

open access: yesMultiscale Modeling & Simulation, 2014
Numerical homogenization, i.e. the finite-dimensional approximation of solution spaces of PDEs with arbitrary rough coefficients, requires the identification of accurate basis elements.

Hardening Parameter Homogenization for J2 Flow with Isotropic Hardening of Steel Fiber-Reinforced Concrete Composites

open access: yesCrystals, 2021
Numerical modeling of the stress–strain state of composite materials such as fiber-reinforced concrete is a considerable computational challenge. Even if a computational grid with the resolution of all inclusions is built, it will take a great amount of ...

INFLUENCE OF HOMOGENIZATION METHODS IN PREDICTION OF STRENGTH PROPERTIES FOR WPC COMPOSITES [PDF]

open access: yesApplied Computer Science, 2017
In order to reduce costs of experimental research, new methods of fore-casting material properties are being developed. The current intensive increase in computing power motivates to develop the computer simula-tions for material properties prediction ...

Clustering solver for displacement-based numerical homogenization

open access: yesTheoretical and Applied Mechanics Letters, 2022
Based on strain-clustering via k-means, we decompose computational domain into clusters of possibly disjoint cells. Assuming cells in each cluster take the same strain, we reconstruct displacement field.

Numerical Methods for Multilattices [PDF]

open access: yes, 2012
Among the efficient numerical methods based on atomistic models, the quasicontinuum (QC) method has attracted growing interest in recent years. The QC method was first developed for crystalline materials with Bravais lattice and was later extended to ...
