In all cases, it is helpful to established a theoretical link between the functional properties of the surface and its micro- physiognomy[2].
As a material removal process, there are two key factors in the grinding process to affect the surface performance: the geomorphology of the wheel and the chip formation process involved[3], which considers the interaction of the workpiece surface and the abrasive grains.
As the technology of SHSP grinding emerges, the angle of α has changed the contact area between the wheel and the cylindrical workpiece, which could be attained through analyzing the grinding parameters affecting it.
According to the application rang of SHSP grinding, the value of α is set to ±0.5°, which is the main factor to affect the contact area to be increased.
The surface quality has been improved in theory based on the number of cutting from effective particles in SHSP grinding while grinding in the same wheel speed and other factors compared to SHS grinding.

The Quenching and Partitioning (Q&P) process is a promising method for developing steels with superior mechanical properties.
These microstructural changes influence the mechanical properties of the Q&P steels.
The influence of these processes on the mechanical properties, measured via microtensile testing, is discussed.

The efficiency of electrolytic process is affected by many factors including the type of electrodes [4, 5].
But still there is a lack of research in the field of electrochemical properties of TiO2-x electrodes made by vacuum annealing.

The simulation tests reveal that the biaxial stresses have strong influence on the fracture properties of glass.
Numerical Model In RFPA 2D , the solid or structure is assumed to be composed of many elements with the small and fixed size, and the mechanical properties of these elements are assumed to conform to a given Weibull statistical distribution as defined in the following: ( ) m m u u u u u m uf      −      = − 0 1 00 exp (1) where u is the parameter of element properties (such as strength or elastic modulus); the scale parameter u0 is related to the average of element parameter and the shape parameter m defines the shape of the distribution function.
Fig.3 is the compare of the stress intensity factors while numerical specimens' fracture under different biaxial stress states.
The result certifies that biaxial stress truly affects the brittle material's fracture-toughness character, and it also illustrates that the evaluation of the fracture cannot simply rely on the stress intensity factors under the complex stress states.
And it further illustrates that the evaluation of the fracture cannot simply rely on the stress intensity factors criterion under the complex stress

Pan and Sheppard [5] calculated stress intensity factors for crack propagation through the plate by numerically utilizing finite element analysis.
Table1 shows mechanical and fatigue properties of the sheet and nugget.

Because of these factors, the deformation of spot-weld specimen is very complex due to these factors, especially around the nugget.

Introduction Freeze-thaw damage of concrete is known as the damage occurs in saturated concrete due to the freeze-thaw circles which is a significant affecting factor on durability of concrete structures.
They believe that the main factors affecting the durability index is the average spacing and water cement ratio, and the main factors affecting the average spacing is the air content and water cement ratio.
They investigate the influence of freeze-thaw cycles on the mechanical properties of concrete (compressive, tensile and shear strength, elastic modulus, the Poisson coefficient and shear modulus).
And they also study the relation between damage caused by mechanical properties and the microscopic properties of high strength concrete and ordinary concrete.
The empirical model, due to regard the resistance mechanism as the macro guidance and seize the main factors of affecting the frost resistance and through regression analysis of experimental data, establishes the macro mathematical model.

We have developed a new Ti alloy, Ti-15%Zr-4%Nb-4%Ta alloy (Ti-15-4-4) that showed higher biological safety and mechanical properties than the currently used Ti-6%Al-4%V alloy.
These results indicate that the new Ti-15-4-4 alloy has a potential for use as implants and has the advantage of improved mechanical properties described in earlier studies.
Newly formed bone only at sites not affected or only negligibly affected by preexisting cortical bone was used and the bone circumference was visualized.
Implant surface modifications are done to increase surface roughness, increase surface area, and provide bioactive and osteoconductive properties.
It is also conceivable that the topography of blasted implant surface can allow the entrapment and concentration of bone growth factors (e.g., bone morphogenetic proteins) circulating in the medullary cavity causing the surface to be osteoinductive.

The vibration properties under sine excitation and random were simulated by the Matlab Simulink Software.
The characteristics of friction influence resulted from comprehensive functions of all factors, such as types of excitation, excitation amplitude and frequency and the location of friction.
It is well known that structural vibration under load will accelerate structural fatigue failure, affect directly the performance of mechanical systems and reduce comfort of the operators.
However, due to the complexity and nonlinear of friction, it is still not very clear that how does friction force affect the structure vibration.
