Introduction The idea of fluid flow through/past a porous media finds its importance in applied sciences and engineering fields such as filtration, acoustics, geochemistry, soil mechanics, rock mechanics, petroleum engineering, biomedical engineering, structural engineering, and in the field of geosciences like hydrogeology, petroleum geology, geophysics, and also in the inter disciplinary fields of biology and biophysics, material science.

So, the recycling seems to be practical and valuable, and even contribute to resolving the current contradiction of supplying gap in China rare material resources [2].
According to the national guidelines, the recovery rate of scrapped auto has to achieve 95% and the reuse rate of scrapped materials has to exceed 85% in 2017 [3].
Its transfer efficiency can reach more than 90% if oxygen concentration is enough and the efficiency is relative high in environment materials.

As a result, new materials are introduced and IC manufacturing processes become more complex.
But they present significant differences in both materials, the contamination level near to the surface and the penetration depth.

Organization of the Text The Establishment of FEM 1.1 Geometrical Model Most floating floors are composed of two layers made up of different materials: bottom layer and surface layer.
Both bottom and surface layers are actually composed of multiple layers of materials.

Composite materials are one such category of materials that plays a momentous role in current and future products.
The failure theories [6] for the composites are therefore a little more complex than those for isotropic materials.

Introduction The increasing use of composite materials in structural applications has generated considerable interest for the development of techniques for predicting the structural response under various loading conditions.
Failure mechanisms in composite materials are much more complicated than those in a structure made of a homogeneous and isotropic material because of aniso-tropic behaviour.
These materials are highly susceptible to intra-laminar and inter-laminar drawback like matrix cracking.
