The woven and 2D braiding fabric prepreg were both selected as top face and inner face materials , respectively, and the carbon fiber woven fabric prepreg was chosen as inner part materials.
It is a common practice to use the materials with light weight, high stiffness and bending strength for increasing damping performances.
The choice for the high speed moving structural materials has shifted from almost metallic structures to advanced sandwich composites[3].

Classical surface NDT methods are thus advantageously supplemented by surface prints in selected places of the inspected material.
The replica material does not shrink, is flexible and non-flammable.
For easy application of the replication material, an application gun is available to the user, in which the two components are mixed, and a silicone rubber-based replica is formed.
Both types were compared with each other during printing of the defects detected by the fluorescence magnetic method on the surface of the rotor bearing journal, Fig. 2.

A perfect viscoplastic analysis is also carried out in linear strain hardening (H'=0) materials.
The first case is the perfectly visco-plastic material in which � = 0.

Now, magnesium and magnesium alloys have been extensively applied to the fields, such as, navigation, astronavigation, "3C" products in automobile industry and military industry, and climbed up to the top materials to decrease energy exhausted and protect environment.
Currently, countries enjoying developed industries have already engaged in the study and exploration of processing materials of magnesium alloys with high capability in deformation [3].
Materials and Methods for Experiment The chemical constitution of the AZ80 magnesium alloy, provided by the Key Lab of Electromagnetic Processing of Materials of the Ministry of Education at Northeast University, in the experiment was displayed in Table 1.

It is thus a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across the material.
For semiconductor materials the coefficient may be between 100μV/°K and 300μV/°K, in any case still very small.
The Seebeck voltage does not depend on the temperature distribution along the conductor but only on the temperature difference between the ends For comparison purposes the usefulness of thermoelectric materials for electricity generation as well as for heating and cooling can be characterized using a figure of merit incorporating these properties.
The figure of merit Z of a thermoelectric material is a measure of its efficiency as an energy conversion component and is defined as : Z = Σs2/ λ (2) Materials with high thermoelectric figures of merit are typically heavily doped semiconductors and for many years the best materials had a figure of merit of around 1.
Recent advances in materials science have increased this number to around 4.
