They also put forward that bolted joints as virtual materials which have equal cross section, then base on engineering data parameters to set up dynamic model.
Su Tiexiong [48] determined the nature of the specific materials through the results of modal experiment in 2001.
Tian Hongliang [39] in 2011 put forward a kind of dynamic parametric modeling method based on virtual material, which was that regarded the bolted joints as a cross section of the virtual material, then thought that joint part unit was equivalent to a fixed connection of virtual materials and binding surface of two parts, and base on engineering data parameters to set up dynamic model and solve the problem of the dynamics model of engineering practicability.

Kwan and Zhirui Wang* Department of Materials Science and Engineering, University of Toronto, 184 College St., Toronto, Ontario, Canada *zhirui.wang@utoronto.ca Key words: Cyclic deformation, ECAP (Equal Channel Angular Pressing), ARB (Accumulative Roll-Bonding), cyclic stability, cyclic softening ratio Abstract With the increase of interest in using ultra-fine and nano-grained metals for structural purposes, the need to build on the knowledge pool regarding the response and behaviour of those metals under a mechanical load becomes more vital.
However, it is well known that, especially for this type of materials such as the ECAPed and ARBed materials, the thermo-mechanical history affects the mechanical behaviour of the product strongly.
There are many different methods of producing products with uf and nc grain sized metallic materials.
From the curves in Fig. 2, for Type B materials, with very small applied plastic strain amplitudes, the materials do not demonstrate apparent softening or hardening behaviour.

Analysis of Affecting Factors and Countermeasures of Innovative Education in Military Academy Xu Hang and Zhou Mingqiu The First Aeronautical Institute of Air Force, Henan, Xinyang, 464000 email:hangxhappy@163.com Key words: Innovation Education; Military academy; Education Mode; Evaluation System Abstract.
Ways and methods to solve the problem Innovative education is complete system engineering, involving many aspects such as the operating system, management mechanism, teaching links, teaching contents, teaching methods, teaching aids, examination system, evaluation system, etc. 1.
(1) We need to construct a multi-dimensional and interactive classroom teaching system, change the past teaching method of “three centers” (with teachers as the center, the classroom as the center and teaching materials as the center) and attach importance to the subject role and dynamic role of students in learning activities

It is not hard to know that in the product symbol blending with the image, the image corresponds with the designatum of the product symbol, which means the image is attached to the designatum and is the key to convey the semantic meaning.
This information includes the physical materials and psychological feelings, such as the pictures, the sound-visuals, the sense of excitement, the sense of comfort and so on.

The surface buoys can be made with composite materials and be fixed on the pile cap or anchorage by mooring.
When the ship is hit, the ship slowly forward through dragging anchorage by the intercept cable, which can consume a lot of energy and play a role of intercept and anti collision; (4) There is a large range of effective protection to assure P15 and P16 piers against ship collision and has some protective effect for the remaining side pier; (5) The collision avoidance system is suitable for all ship types, especially for the ship with ball nose bow; (6) because the key components of the entire system is the cable, once the cable breaks due to corrosion or the occurrence of ship collision, the job of changing cables can be carried out in low water or dry season.

With the principle of minimizing the magnetic energy (under a given external magnetic field ), the material’s magnetization direction (θ) can be determined and the total magnetic energy can be calculated [7-10].
Therefore, Ku is an important material property playing a key role in the magentic-field induced martensite reoreienation where Ku has to be larger than energy dissipation of the martensite twin boundary motion [7].
