Biomechanical compatibility is based on similarity of mechanical properties of implant material and bone tissue.
Thus the most important mechanical properties of metallic materials for bone and dental implants are low elastic modulus and superelasticity.
High concentration of oxygen leads to embrittlement of Ti-Nb alloys, so it is important to retain oxygen and other impurities at lowest level so they do not affect plasticity and functional properties of the alloys.

Various factors influence the integrity of steel structures, making damage predictions particularly challenging, especially with respect to environmental conditions.
Fatigue and environmental factors significantly affect the durability and performance of steel structures, underscoring the need for effective crack prevention [3, 4].
The material properties of the plate include a Young's modulus of 196.5 GPa and a density of 8000 kg/m³.
It remains unclear whether this interference is due to the material properties of the patch itself or its physical characteristics, such as thickness.
Further studies are needed to explore how these factors influence the PZT-SLDV signal.

Introduction
Natural stone materials with good properties, its texture, resistant to wear and corrosion, become the world's most important construction materials since the ancient times.
With different content of its composition, the physical and chemical properties of the stone material are quite different.
The factors influence the fracture of the granite thin slab can be divided into the external factors and internal factors.
The external factors in the process of grinding are force and vibration.
The internal factors are native cracks, micro voids, grain boundaries of the granite thin slab, etc

Method
Influence of magnetic field on properties of mine water
Experiments were divided into three groups.
Factors affecting the effect of coagulation The influence of magnetic intensities on coagulation The mine water was magnetized for 4 min under the intensities of 0.1T, 0.15T, 0.2T, 0.25T, 0.3T, 0.35T, 0.4T, 0.45T and 0.5T respectly.
The three levels of each factor were chosen by single factor experiment (Factors of orthogonal experiment and their levels are shown in Table 1).
Table 1 Factors of orthogonal experiment and their levels No.
Factors affecting the effect of coagulation The influence of magnetic intensities on coagulation Under different magnetic field intensity but same time, adding same volume of aluminum chloride (PAC) solution to carry out coagulation test, the results were shown in Fig. 3.

The factors such as temperature and pressure of the inside air and the kinetic parameters of the ball joint that influence natural frequencies and vibrational modes are considered.
Take account of the process, stress characteristics and other factors, some T-tubes and bends should be thickened that makes the cross-sectional size of the duct not uniform.
The properties of A312 TP321 and 2042 T42 at typical temperatures [8] are shown in Table 2 and Table 3.
In the calculation process, the properties at other temperature points can be obtained by linear fitting.
Influencing Factors Temperature and Pressure Thermal stress and compressive stress due to high temperature and pressure gas in ducts will affect the mechanical properties of the materials directly [9], thus affecting the natural vibration characteristics of the structure.

Introduction
The hot and humid environment caused by geotherm and groundwater is the main factor that affects the physical and psychological health and the working efficiency of the workers working in deep underground conditions.
Water leakage of the surrounding rock, heat radiation of the high-temperature rock and the interaction of moisture with heat are the main factors caused the high temperature and humidity.
Experiment Materials The cementitious material used in the experiment was P.O.42.5 ordinary Portland cement whose physical properties are shown in Table 1.
Finally, the expected composite material was produced after the complex was maintained for 48h under natural condition. 1.2.3 Testing of Mechanical and Physical Properties of the Foamed Concrete By using trabecular single-point loading method, the flexural strength of foamed concrete sample with a size of 40mm × 40mm × 160mm was tested.
However, the strength of the foamed concrete is affected by such factors as the performance of the concrete, water-cement ratio, foam amount, foam size and the distribution of the foam in the concrete.

There is therefore a need to improve the physical and mechanical properties of details surface layers [1 - 6].
Generally, the quality of plasma coating is a comprehensive integrated parameter which depends on many factors of the manufacturing process.
Therefore, it is urgent to find a comprehensive solution to the problem of ensuring the required level of the coatings physical-mechanical and performance properties.
Joint analysis of technological factors allows obtaining the surface roughness within Rz = 30... 100 µm.

Especially, the mechanical properties of Si3N4-based ceramic have been enhanced by adding the second phase (TiC, SiC, TiN, etc.) in the form of whiskers or ultrafine particles, and obvious improvement has been achieved [7,8].
However, the improvement of mechanical properties does not necessarily mean the better wear performance of Si3N4-based ceramics [9].
Experimental The chemical composition and mechanical properties of ceramic tools are shown in Table 1.

One of the limiting factors in the use of Super304H is their susceptibility to the water vapor oxidation on the steam-side.
The properties of the materials at 600℃ have been listed in table 1.
Table 1 Materials properties at 600℃ E(GPa) ν α(10-6) Fe3O4 210 0.29 9.1 Cr2O3 230 0.25 5.4-7.5 Super304H 158 0.3 18.7 Thermal stress Fig. 4 Thermal stress distribution at 600℃ Figure 4 revealed the thermal stress distribution of the oxide layer and S304H substrate.
In the literature, it has been reported that interface between the inner and outer layer should be the easily failed locations because of the weak adhesive force and lower deformation properties of oxide layer.
Thus, the value of the stress also had been affected by the variation of the slope.
