Introduction The demand for materials with keeps good mechanical properties at high temperatures is increasing in the aerospace industry.
Currently, the dominant materials in the hot zone of aeronautical turbines are metallic superalloys that withstand temperatures above 1000 ºC [1].
Among Ceramic Matrix Composite Materials (CMCs), those with a silicon carbide (SiC) matrix are the most used for the manufacture of aeronautical engines [5].

The main problem is that these materials are very reactive and may undergo environmentally induced degradation during service.
Corrosion of magnesium alloys was introduced as a new degradation method for temporary implant materials in orthopaedic surgery [4].

The interaction of these shock waves with thickened boundary layers will cause larger flow separation zones that are responsible for considerable loss of mass flow, total pressure and several other effects, such as shock movement and higher surface heat flux into the structural materials of the engine.

With the improvement of science and technology and people's living standard, the ability of prevent earthquake disasters has been improved, the structure of the damping control technology has get more and more researchers’ attention both at home and abroad due to its characteristic of economy applicable energy consumption, simple structure, convenient maintenance, and the better damping effect. so the technology has become an effective method to dissipate earthquake energy.
Mild Steel Damper Material Selection The mild steel damper is made from steel Q235, material constitutive relation uses ideal elastic-plastic material model , the relevant parameters in Table 1.In the Table 1, is yield stress, is ultimate strength, E is modulus of elasticity, is yield strain and is ultimate strain.
Flange plate thickness and length of the specimen are same to H -type dampers ; constitutive relation of other materials using an ideal elastic-plastic model , the parameters in Table 1.
