A bridging multi-scale method is proposed for the analysis of a class of localization problems in which the micropolar-continuum model is used to describe the localized deformation and the dynamic failure occurs only in a small number of localized regions. It starts with a concurrent discretization of the entire domain with both coarseand finescale finite-element meshes. The coarse-scale mesh i...

As a common geological material, soil is key aspect of construction engineering. Soil has typical multi-scale characteristics, but current methods analyze these characteristics only in regard to geometric space. More exploration the coupling influence mechanism basic properties particles on microstructure and macroscopic needed. This study analyzed scale mineral composition surface energy at mi...

In this study, a multi-grid sampling multi-scale (MGSMS) method is proposed by coupling with finite element (FEM), extended (XFEM) and molecular dynamics (MD) methods. Crack studied comprehensively from microscopic initiations to macroscopic propagation MGSMS method. order establish the relationship between model, FEM used transmit displacement boundary conditions atomic model XFEM feedback cra...

prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. a proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. the main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...
