Introduction Many porous materials, such as filter materials made of sintering metals, lagging materials, fireproof materials and so on, are utilized for various fields.
The authors[5],[6] also have dealt with statical problems and dynamical ones of axisymmetrical shells made of porous materials.
Then in this paper the dynamic problems of non-homogeneous (the functionally graded) porous shells of revolution made of such materials are treated.

Fig.2 is the element model diagram of graphite ceramic extrusion die materials, the most inner layer and the most outer layer are the graphite dies, middle is ceramic composite materials.
The Compositional design of ceramic die materials In order to avoid the longitudinal crack of ceramic extrusion die after hot pressed sintering, the thermal expansion coefficient, elastic modulus and poisson's ratio of ceramic extrusion die material are the design variables, and the largest tensile stress less than allowable stress of ceramic die materials is the objective function.

Introduction With the progress of science and technology, the requirements on new materials are higher and higher.
The research of mechanical property is the basic for the application of the structure materials[2].
The SiCp/ZAlCu5Mn composite materials were fabricated by melt mixing method.
The microstructure of SiCp/ AlCu5Mn composite materials is analyzed by EPIPHOT-300U inverted microscope model.

Compared to Si [1], III-V materials and Group-Ⅳ alloys have much higher electron and hole mobility.
Therefore, it is of great significance to study the bowing factor of lattice constant of alloy materials for understanding the structural properties of materials.
