Generalized Multiscale Finite Element Methods with energy minimizing oversampling
International Journal for Numerical Methods in Engineering, 2018 SummaryIn this paper, we propose a general concept for constructing multiscale basis functions within Generalized Multiscale Finite Element Method, which uses oversampling and stable decomposition. The oversampling refers to using larger regions in constructing multiscale basis functions and stable decomposition allows estimating the local errors.

Size-dependent heat conduction of thermal cellular structures: A surface-enriched multiscale method
Defence TechnologyThis paper examined how microstructure influences the homogenized thermal conductivity of cellular structures and revealed a surface-induced size-dependent effect. This effect is linked to the porous microstructural features of cellular structures, which

A mixed multiscale spectral generalized finite element method
Numerische MathematikWe present a multiscale mixed finite element method for solving second order elliptic equations with general $L^{\infty}$-coefficients arising from flow in highly heterogeneous porous media. Our approach is based on a multiscale spectral generalized finite element method (MS-GFEM) and exploits the superior local mass conservation properties of mixed ...

Multiscale Static Compressive Damage Characteristics of Kiwifruit Based on the Finite Element Method
FoodsIn the handling or processing process, fruits are easily crushed by external loads. This type of damage in fruit often leads to the internal pulp browning and rotting, with the severity largely dependent on the fruit tissue’s geometric and mechanical ...

Identification in multiscale thermoelastic problems
Computer Assisted Methods in Engineering and Science, 2017 The paper deals with the identification in multiscale analysis of structures under thermal and mechanical loads. A two-scale model of porous materials is examined. Direct thermoelastic analyses with representative volume element (RVE) and finite element
