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

Volume fraction of the composite affects effect of aging hardening, but does not change trend of the aging hardening curve.
Therefore, it is necessary that aging behavior and its influencing factors of AZ91D alloy and Al2O3-SiO2(sf) / AZ91D composites were investigated at great length in order to exploit the mechanical property potential of the alloy and composite.
It was found that there were two aging peaks in aging hardening curve of both AZ91 alloy and SiCp/AZ91 composite when the mechanical properties of SiCp/AZ91 composite fabricated by powder metallurgy were investigated by Chua B.W.[10].
In this study, aging behavior of Al2O3-SiO2(sf) / AZ91D composite was investigated in detail by using DSC and TEM, and aging hardening curve with three aging peaks was gained, which has positive significance for improving mechanical properties of Mg-Al alloy and Mg-Al alloy matrix composites.

From Table 7 we can see that use 7d compressive strength of coal gangue concrete as assessment indicators in the range of experimental factors levels, the order of the factors effect is Gangue> Slag>Fly ash, optimal scheme is A2B2C2; use 28d compressive strength of coal gangue concrete as assessment indicators, the order of the factors effect is Fly ash > Gangue > Slag, optimal scheme is A2B3C2.
By adjusting the three factors component, it can be control the gangue concrete mechanical properties and impermeability in a better level and improve the durability of concrete, full use of waste, protect the environment.

The choice of factors was made based on material properties.
Thus, only seven factors were used for variation that varied at two levels.
Tables 1 and 2 show investigated factors and selected levels of variation for applying substrate and code.
You can evaluate the linear effects of factors mixed with pair interactions using contrast.

This work investigates the disinfection properties of ZnO nanofluids, especially the change of ZnO disinfection properties when facing different shaking speeds of incubator (50rpm, 100rpm, 200rpm and 300rpm).
Nano-scaled materials with at least one critical dimension less than ~100nm, if properly engineered, have unique electrical, thermal, mechanical, chemical, and biological properties.
Previous work showed that there were many factors that would affect the antimicrobial activities of ZnO[7, 10].
These factors include particle concentration, particle size, surface area, temperature, lattice constant, and presence of surfactant.
Though many antimicrobial factors which could affect the antimicrobial activities of ZnO were studied, there is no work studying on the effect of shaking speed of incubator, which is the main objective of this work.

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.

The thermal properties of the joined metallic glasses were the same as that of the parent metallic glass.
The metallic glasses show excellent physical, chemical and mechanical properties [2] due to its unique structure compared with conventional crystalline alloys, such as high stiffness, high strength, high wear and corrosion resistance, good soft-magnetic properties, which means bulk metallic glasses have widely potential applications.
The result reveals that the metallic glasses before and after ultrasonic welding have the same thermal properties.
The factors affecting sufficient atomic distance are the surface oxide films and contaminants, the roughness of the bonding surface.
The thermal properties of Fe78Si9B13 metallic glass were maintained
