In the last 30 years, because size, structure and material were constrained by the level of science and technology, the research of the pressure hull fell into bottleneck.
As the technology of composite material pressure shell had not yet stood the test of time, the titanium alloy would be the best quality engineering materials considering weight and strength.
(8) When m=0, material would become the ideal elastic-plastic.

Some reports show that Acheson graphitization furnace with SiC synthesis materials as insulation material can produce not only graphite but also SiC.
So the finite element method is selected to analyze Co-production furnace that graphitization process apply LWG method and the insulation material is SiC synthesis materials [8].
According to the technology analysis, the temperature field is unsteady and the synthesis materials' properties are nonlinear.
