GEFMA’s Directive 100-1 [3] defines FM from a science and research aspect coupled with an understanding of market participants.
Given the authors subject knowledge there appears to be very limited research material available on how to strategically develop growth in the FM-sector, especially not in the area of FM in Data Centres.

Key Laboratory of New Electric Functional Materials of Guangxi Colleges and Universities, Guangxi Teachers Education University, Nanning 530023, China.
Introduction As one of the most promising high-temperature structural materials, trialuminide intermetallic compound Al3Ti is of great interest due to the high specific strength, high elastic modulus, low density, good thermal conductivity and high melting point.
Besides, high pressure leads to the phase transition and changes the physical and chemical properties of materials.

According to the Fig.2 and Fig.3[5], calculating process of the specification parameter of the 8inch lenticular gasket is as follows:
(1) Calculations of d2, d5, x
Inner diameter of an 8inch flange : di=409.5mm
Wall thickness: t=23.8mm
d2 =565mm
d5 =530mm
x=48mm
PS: d2, d5, x is ensured by the proportional relation of the correspond value of inner diameter of the standard flanges.
During the butt jointing of pipelines, the gaskets are interchangeable parts, and flanges are reusable parts, so the material of flanges should be harder than the gaskets to guarantee the soft one can reach the yield limit and avoid the excessive deformation of flange seal surface.
In the seal material of contact surfaces, the gasket is made by soft material, so the Rc value should be assigned as yield strength(205 Mpa) of stainless steel 316.

The frequency range of AE, a transient elastic wave under material deformation, is usually
100kHz-1MHz and its displacement is 10
-10-10-13m.
While the AE in a real structure is emitted from the inside of material, the AE in PLF is emitted on the surface of material.
The resonant frequency depends on both the length of a cantilever and material properties of an optical fiber.
