Some other parameters affecting TSIF, such as segmentation crack depth and convection severity, were also discussed.
Introduction Protective coatings have been widely used in thermal environments to improve certain surface properties of the substrate, e.g., thermal, corrosion and wear resistance.
The transient thermal stress intensity factors (TSIFs) were evaluated using finite element method.
The main dimensionless data concerning material properties and geometrical parameters in our calculations are tabulated in Table 1.
In terms of the differences in thermo-physical properties of coating and substrate, circumferential stress discontinues at the interface as expected.

The interface transition zone (ITZ) has a significant impact on the concrete’s mechanical properties and fracture modes.
The results show that ITZ’s strength and elastic modulus have a certain effect on the mechanical properties and fracture modes.
The characteristic of ITZ significantly affects the mechanical properties and fracture process of concrete.
Lybuimove firstly studies the mesostructure concrete and puts forward the concept of ITZ, takes ITZ as the leading factor to concrete’s mechanical property [4].
Compared with the mortar, the parameters of ITZ, including low strength, low elastic modulus and high permeability, influence concrete mechanical properties [7].

The structural configurations of atom constituting materials are one of the fundamental
factors in the study of physical properties of materials.
Introduction Techniques to understand and control microscopic systems are important because they provide ways to control material properties.
The following are important geometric factors affecting the material properties: While pores, dislocations, cracks, and grain boundaries affect the material properties on a micro-scale, the arrangement of atoms, order of stacks, and lattice mismatches have influences on a nano scale.
Moreover, there are important applications based on geometric properties for spatial problems.
In addition, the grain boundaries and properties of a material can be also analyzed under the different circumstances such as temperatures, stresses, and shock waves.

There are many factors affecting the performance of brake pads, particularly their friction and wear rate [4].
These factors are statistically significant at the 0.05 level with the current model.
A summary of the measured properties that are influenced by the mixing time No.
However, every specimen has a slight difference in physical properties, given the rather similar wear rate, as noted earlier [11], A variation in porosity affects the performance of brake pad less than does a variation in hardness.
Thus, the consideration of physical properties focused on hardness.

There are many factors to affect the ER damper properties, such as construction parameter, inspire parameter and ER properties [8-9].
This paper focuses on the researching of relationship among shear stress and frequency, velocity, displacement and ER properties through simulation.
We can see from the formula that damper strength is close relationship with construction factors(d, L, D, h),surroundings factors(V, f, v),and ER parameter(α, β, η0).
Third, surroundings factors (V, f, v) decide damper strength of damping device when front parameter were defined.
This paper focuses on the research of damper strength -- velocity, damper strength – drift properties of shear ER fluid damper.
