Through this hierarchical multiscale simulation, composite macro-performance can be predicted by micro-scale parameters, this relationship will give a reference for composite design and optimization.
In the literature, the effective macro-scale diffusion coefficients are now well established, while uncertainty remains concerning the relationship between the effective thermodiffusion coefficient and micro-scale parameters (such as pore-scale geometry).
The efficacy of the proposed study is illustrated by investigating the effective response for several network realizations, incorporating the influence of different micro-scale parameters, such as fibre hygro-thermo-elastic properties, orientation, geometry, areal coverage.
The MFPM enables us to quantify soil heterogeneity at two scales: the micro-scale parameters describe on average the effects of pore network heterogeneities on the two-phase flow pattern; the macro-scale parameters indicate the variability of permeability at the scale of interconnected pore networks.
Flow in porous media, diffusion of gases in complex pore structures and membrane flux in water desalination are examples of the application of this important micro-scale parameter.
The experiments of the stiffness and rotation error of the spindle show that the deflection of the shaft resulting from the calculating parameters in the micro scale is very close to the deviation of the spindle system.
Owing to that concrete is a severely heterogeneous material at micro scale, the relationship between stress wave parameters and microstructure of concrete such as pores and preexisting cracks in concrete is still unclear, which limits the generalization of monitoring system in different concrete structures.
The selected ten high-rise residential sites in inner-city Shanghai were grouped in four urban climate zones (UCZ) based on urban cover and urban structure, in order to control the local-scale urban influence on the measured micro-scale wind parameters for the sites in each UCZ.
An array of micro scale dimples were then fabricated on the cutting tool using the optimized parameter levels.
The contact non-linearity is governed by micro and meso-scale parameters (geometry, roughness, local pressure, etc).
In non-classical micro-beams, the governing Partial Differential Equation (PDE) of motion is obtained based on the non-classical continuum mechanics which introduces material length scale parameters.
