Experimental Material and Method The test material was steel 40Cr, initially quenched and tempered.
The raised material with repeated plastic deformation caused by the friction leads to work hardening, cracking, spalling and then generated chips.

(1) Absorbing materials Absorbing materials can absorb incident electromagnetic wave and consume electromagnetic energy through energy transform or make electromagnetic wave disappear because of interference.
It is a mature absorbing material and attracts much research.
With the information security becoming more and more important, electromagnetic interference and anti- electromagnetic interference has became an important part of science research.

Table 2 The material properties of welded metal bellows Material Properties Young's Modulus (pa) Poisson’s Ratio Density (kg/ m3) Limit of Yielding(Mpa) Plastic Modulus(Mpa) Value 1.93× 1011 0.3 7.80× 103 207 207 An algorithm for generating 3mm tetrahedral mesh for welded metal bellows is adopted. 181 710 cells and 90466 nodes are divided for single layer bellows, 351460 cells and 185540 nodes are divided for double layer bellows.
Table 2 shows the material properties of welded metal bellows.
So, the material, the quality and the welding technology should be considered in the welded metal bellows designing.

the static stress analysis of pipeline with frusta when collapse and gulch was occurred The steel pipeline[5] was studied that the material is X-70 steel, E =210Gpa, , Yield limit is MPa;ultimate strength is MPa , inner radius is m,outer radius is m, the buried depth is 1.6m, The selection of steel pipeline calculation model is like other structures [5], be based on true build object diagram, the few impact factors are abandoned in drawing calculating diagram.
From the results the following can be drawn ,that the pipeline with frusta material was entered the yield stage as the collapsed pipeline length L =28m, and then the pipeline was occurred in pipeline damage. similarly, in gully state, L =111m.
In the static calculation, pipeline collapsed length is L =28m, the material yield stage is entered, and then pipeline damage is occurred, so the L =28m should be more concerned about our study collapse failure length.

This material is also useful as a substrate for growth of gold and silver nanoparticles [6-7].
The EMM system is capable of determining local complex permittivity values for different materials by measuring the quality factor (Q-factor) and the resonant frequency shift of the resonant coaxial probe as the tip-sensor approaches the sample surface interacting with it by the evanescent wave.
For material that absorbs laser energy internally, the heat source is given by Eq. 2.

Fig. 7 The nodes of boundary between pile and soil The assembling of the calculation model of soil and pile body: Because the pile body and the soil are two different materials, the pile body is medium bearing loads, when building the model, this should be considered.
After combining the model of pile body units with model of soil units, according to the conditions of different medium, the characteristic of material is separately input, so it is formed that the computing model of the limited unit analysis about effects of pile and soil work together.
