Abstract.
Introduction CAI(Compression After Impact) values obtained by NASA (or SACMA) test standards usually are used as the very important index for material scientists to develop new composite systems and aircraft designers to select materials.
During the past 20 years CAI has been used to evaluate the behavior of composite materials to withstand impact.
Preliminary study on evaluation system of composite materials to withstand impact Recently Authors [2-5] carried out a lot of experimental study on the evaluation system of composite materials to withstand impact.
To be published in Journal of Composite Structures Vol 75, 2006 [5] Z.Shen, P.H.Chen, S.C.Yang.

Long-term
durability of advanced polymeric materials in hygrothermal environments is of vital concern.
Pioneering work [1-6] has been conducted on diffusion and viscoelastic deformation in polymeric materials.
The effective time theory to predict long-term behavior of polymeric materials experiencing physical aging from short-term experiments [13] is analogous to the method of reduced variables for thermorheologically simple materials [7], both of which may be described with the concept of a material clock [8].

Introduction In China, organic heat preservation materials have been widely used in Exterior Insulation And Finish System, however, potential security risks exist in fire safety since these organic materials are flammable [1-4].
Cementing materials were composed of rapid hardening sulphoaluminate cement of 42.5R, fly ash of grade I and sodium silicate.
In material mixing process, surfaces of the bead are coated with cementing materials.

However, for the "single factor" material model, the correlation between material parameters (D
,n) and temperature is different for various materials.
Some materials express weakly temperature dependence (D and n are temperature independent) [4], but other materials express stronger temperature dependence (D and n are temperature dependent) [5].

Syntheses of new materials include synthesis of porous carbon and porous metal organic frameworks materials and construction of battery structure use polymer organics as matrix.
Jiang, JW, et al. [1] summarized the function of molecular simulations in application research on nano-porous materials in energy area, and proved that molecular-level studies can bridge the gap between physical and engineering sciences.
Resulting CDC replica materials show high methane and n-butane capacity.
Results showed that the cell performed well without exhibiting water-flooding. 2.2 MOFs materials Porous MOFs materials experienced great development in the last decades.

Mesoscopic Scale Modeling of “Superplastic” Flow in Geological and Glacial Materials
M.
Extensive studies on the deformation mechanisms in these materials have been conducted since the work of Boullier and Gueguen [1] on geological materials and Goldsby and Kohlstedt on ice [2].
Behavior of many geological materials and ice has been reported.
It is emphasized that in geological and glacial materials the grain size varies from extremely coarse to fine grain sizes.
