In the past decades, composite materials have been widely adopted in aerospace and other engineering fields.
However, laminate composite materials have serious defects, such as a local stress concentration, delamination and weak of thermal resistant.
To overcome these drawbacks, functionally graded materials (FGMs) were proposed recently for high-resistant materials without interface problem because of the gradual variation of the material compositions from a material to another.
Functionally graded materials are proposed for high-heat-resistant demands.
The FGM is usually a mixture of two materials: ceramic that is capable of withstanding severe environment, and metal that acts as a structure to carry aerodynamic load.

Along with the arrival of the comprehensive cultural age in which natural science is mutually colliding with humanism science, technology and art, thinking in images, and rational thinking, etc.
Concepts of Modern Ceramic Art and Outdoor Environment In essence, modern ceramic art is inheritance, development and innovation of the traditional ceramic art, or creation media which focuses on the ceramic materials.
In comparison with metals, plastics, concrete and other cold materials, soil makes it easier for people to generate a feeling of close relationship.
Moreover, the natural beauty of the texture of soil can never be replaced by any other materials.

Dual Boundary Element Analysis for Time-Dependent Fracture Problems in Creeping Materials E.
This paper presents the development of a new boundary element formulation for analysis of fracture problems in creeping materials.
Once such problem is fracture in creeping materials.

Ultrafine Glass Fiber Core Material Produced by Wet method Tengzhou Xu1,a, Zhaofeng Chen1,b, Jieming Zhou2,c, Xueyu Cheng2,d, Wangping Wu1,e, Zhou Chen1,f 1College of Material Science and technology, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, P.R.
In general, the core materials have fibers, powders and foams [2].
Moreover, volume weight (about 150kg/m3) of the ultrafine glass fiber core materials is smaller than that of conventional insulation core materials, such as fumed silica, precipitated silica and so on.
Therefore, molecular collision doesn’t occur in the interior of core materials.

Under this assumption, the properties of the materials are different between the planes on and normal to the isotropic plane.
