The finite element analysis of derrick The steel material properties and displacement constraints of derrick The materials used for JJ225/42-KC type oil derrick are Q235 and 16Mn steel.
This paper uses the method of non-linear calculation in the finite element analysis, but to the physical material properties of derrick, the linear elasticity equations are still used.
Derrick leg pin is used to connect the four feet of bottom of the derrick to the four base structure, all three materials are 35CrMo and modulation processing, the allowable stress []=324Mpa, the stress values of the two dangerous cross-section of square shaft are 146.1Mpa and 165.59Mpa, and the Pins for connecting plate and the leg pins of derrick are 256Mpa and 240.73Mpa respectively, all of them are less than the allowable stress 324Mpa, the result illustrates that all above meet the requirements of the strength.

Studying the effect of doping on BSCCO system gives an opportunity to vary the functional and mechanical properties of the material.
However, it is recently discovered that superconducting foams are superconducting materials of a new kind having interesting properties.
Materials in foam structures can be considered as a novel class among bulks, films, and single crystals [7].
