In order to analyze stress distribution within the restoration and tooth, mechanical properties of materials and tissues, such as Young modulus and Poisson’s ratio were taken into account.
The shape and size of elements is chosen based on different factors, such as geometry, required accuracy of the solution and the nature of the problem analyzed.
Mechanical properties were defined for each of the materials used, based on available literature [6].
Mechanical properties of materials used in the model are given in table 1.

The damage factor can not only change the cohesive zone bonding strength but also affect the energies of separation.
It can affect not only on the maximal strength but also interfacial stiffness.
When the temperature and humidity is the bonding interfacial major damage factors, the interfacial damage factor Hλ is relation to the duration.
The constitutive properties of the bonding interface can be determined through the cohesive zone damage models by the parametersφ, δ, andλ.
Fig. 2 demonstrated the effects the damage factors that can impact not only the initial bonding energy but also the bonding strengths.

The mechanical properties of latex film were measured according to GB/T 1040-1992 mechanical properties test methods for plastics.
But the hydrophile-lipophile property of cross-linker can not only affect the distribution of cross-linking monomers between the oil and water phases, but also affect the distribution of cross-linking monomers in the oil phase droplet.
As shown in Fig. 2, the above two factors can significantly affect the viscosity and rheology of latex.
Thus, it can be considered that the mechanical properties of film are closely related to their cross-linking degree.
(2) The cross-linking degree and mechanical properties of acrylate Latex film cannot be related to the hydrophile-lipophile property of cross-linking monomers.

Cyclic stresses around welding joint-part affect the strength of mechanical components.
Tables 1 and 2 show the chemical composition and mechanical properties of the specimens, respectively.

The effects of carbon nanotubes on mechanical properties were investigated.
The mechanical properties of composites can be affected by carbon nanotubes.
%CNTs 1052 370 5.9 Mechanical properties.
Table 1 shows the mechanical properties of Ti5Si3 and the composites at room temperature.
The phenomena can be due to the factors that the carbon nanotubes dopants distributed uniformly in the composites can lead to dispersion strengthening.

Biomaterial components (PMMA/HA/Sericin) are composite biomaterial that has complemented each other, which HA is able to improve the mechanical properties, biocompatible and osteoconductivity.
Hydroxyapatite (HA) has osteoconductive properties and osseointegration properties [2-4], but pure HA powder was difficult to be shaped due to brittleness characteristic [8].
In fact, the addition of hydroxyapatite in a mixture of PMMA can improve the mechanical properties, biocompatibility, and osteoconductivity [5].
Taguchi is able to analyze the significant influence of many factors (variables) but without considering the interaction between factors, whereas a Factorial design method is able to determine the effect of the significant parameters of the response as well as the influence of interaction between factors [9].

The porosity of quartz mixture, the density, the optimum amount of UPR and the mechanical properties of the SiO2/UPR composites were tested.
It makes significantly differences in the mechanical properties of different gradation plates.
The amount of resin is the most important factor which affects the elastic modulus.
The micro factors becomes large, the mechanism needs further study. 5.
Therefore, the mechanical properties also can be predicted by the obtained formulas.

Cutting properties of interpenetrating network composites are important to ensure machining quality.
Due to the continuous network structure, the INC has good mechanical properties and wide application in various engineering fields[1-5].
On the other hand, because of the non-homogeneous microstructure, the cutting properties of INC are different from the traditional materials in cutting process.
The machined surface quality and precision are also affected by its special properties.
For the purpose of improving manufacturing level, the cutting force properties of INC with double metal phases are researched by cutting experiments.

The dispersion form is actually the one of the factor that will affect the final performance of the nanocomposite.
In present report, mechanical properties of HDPE/EVA/MMT/EFB fibers nanohybrid biocomposite have been studied. 2.
The screw rotation speed in extrusion also affected the flexural properties as reported by B.Mano et, al. [18] where the flexural stress decreased with increasing the screw rotation speed.
