The modern mechanical structures used for automotive and aerospace applications are often characterized by different materials.
The nature of these materials is suitable for many analytical solutions in order to determine their structural behaviour since one of the main characteristics of a composite product is to use the best performances offered by each materials constituting the product [1, 2].
Composite materials are characterized by different mechanisms of damage and breakage.

However, several forms of material deterioration have been reported causing material damages such as delamination, blistering, and breakage of coating layer [1, 2].
Although it is quite applicable to most materials, it is limited to material surface because of exponential decay of the acoustic energy through the material depth.
Comparing to the case of metal, it is quite large and implies that material property has been changed throughout the aging process.

However, most researches on dynamic response of saturated asphalt pavement considered all pavement structural layer as porous materials for analysis convince[5-7].
In the 3D model, asphalt layers are regard as saturated porous materials, while other structural layers are taken as elastic materials.

At present, most flexible joints are employinging elastic material or driving by fluid.
Tab.1 Geometric and material properties of joint Fig.3 The relationship between bending angle and the air pressure It is shown in Fig.4 that with the increase of the air pressure of the single bending joint, the rotation angle of the end face of the single bending joint increase.
