Mechanical strength is one of the key factors for clinical application of injectable carbonate apatite (CO3Ap) cement.
The mechanical strength properties were evaluated by diametral tensile strength (DTS).
In conclusion, revealed that Na CMC does not affect the mechanical strength of CO3Ap cement.
Key factors for a successful clinical application would require ideal materials which could mimic the native bone in both mechanical and osteogenic properties while also possessing good injectability [7-12].

The specific chemical composition and physical and mechanical properties are shown in Tables 4 and 5.
The parameters that have an important influence on the mechanical properties of glass fiber reinforced cement mortar were selected as the influencing factors.
The mechanical properties of GRC specimens were tested according to the L9 (34) orthogonal experiment table.
It shows that the volume content of fiber and the water-binder ratio have a significant effect on the mechanical properties of cement mortar, and the rubber-sand ratio has no significant effect on the mechanical properties of cement mortar.

The mechanical properties of Y-TZP are the highest ever reported for the all-ceramic materials.
Factors Affecting LTD According to researches, factors such as the mean grain size [33-39], the residual stress [40-43], the amount and stabilizer [44], the cubic phase [45] and the addition of Al2O3 [46-49] have a large effect on the LTD of Y-TZP ceramic.
A thermodynamics approach proposed by Lange helps to understand the role of grain size in affecting the LTD of Y-TZP [50].
Factors affecting the free energy components (∆GCH, ∆GE and ∆GS) would have a large effect on the stability of tetragonal zirconia, therefore on the LTD.
Therefore, alumina-zirconia composites combined with good mechanical properties and aging resistance are promising to be used in dentistry.

With the introduction of a mass transport mechanism the entire problem is subjected to a time frame that dictates the time-dependent action of soluted species on mechanical properties.
The simulation of showcases demonstrates crack initiation and crack propagation aiming for the determination of stress-intensity factors and crack-resistance curves.
Finite-element calculations take those mechanisms into account by mass transport simulations and coupling of the local hydrogen concentration to material strength and toughness properties, e.g.
Additional material degradation is superimposed by the local concentration acting on the plastic properties of ψ0m,p.
The mechanical properties were set to E = 210GPa and ν = 0.3, the critical energy release rate was assumed as GC = 10.83kJ/m2.

Surface roughness significantly depends on cutting factors, cutting tool properties, workpiece properties, and cutting phenomenon [1].
Many researchers have investigated the influences of cutting factors on the quality characteristics and the mechanical properties of the machined part using design of experiments (DOE) and response surface methodology (RSM).
The optimal turning factors could reduce the energy consumption and the surface roughness in which they could minimize the environmental impact of turning without affecting the quality of final products.
They found that cutting tool angle was the only significant factor affecting the average surface roughness with the optimal machining condition of 120º used for decreasing surface roughness of the machined part.
The results revealed that the rest factors did not significantly affect average surface roughness.

During the formation of mineralized phases, particle size may affect mechanical properties.
So particle size and distribution was one of important factors for mineralized enamel.
Besides particle size, other factors also affected the particle adherence, such as enamel surface roughness, complicated morphology of particle and so on.
Mechanical properties of Group 2 were close to the polished enamel and Group 3.
However, mechanical properties of Group 3 were the lowest among the Groups, one explanation that in the short time the smaller particles induced crystal nucleation slowly leading to insufficient mechanical properties.

It will therefore be one key factor for future structural applications, to characterise these factors and to understand the current uncertainty in mechanical properties.
Process inherent defects can have a significant influence on the mechanical properties.
Static properties are influenced by a variety of factors, interacting with each other.
The influence of these elements on the mechanical properties is known for e.g. plate material.
The microstructure is therefore another factor affecting the tensile properties.

Tensile fracture morphology is mixed type indicating dimple and cleavage steps, and welding joint have good comprehensive mechanical properties.
The gas metal arc welding (GMAW) is adopted to weld test BS700 steel in the paper, and a series of mechanical properties experiments are conducted, such as the stretch, bend, impact and microhardness of joint, to analyze the microstructure and fracture morphology of weld seam and heat-affected zone.
Figure 1 shows the Chemical composition (mass %) and mechanical properties of experimental BS700MC and WH80-G.
The welding cold cracking is caused by mang factors, such as quench hardening trend, hydrogen content and restraint intensity[6].
