The sequence is important as different materials have different properties.
However, the properties of the kaolin based geopolymer brick is still need to be considered in term of compressive strength, its resistance to the environment and so on before can be used as construction material.

Fig. 9 Pareto diagram and estimated response surface – DP500, 0.6mm thickness From figure 9, one can observe that strong interaction exist between the joint gap and travel speed while travel speed is the most important factor affecting the shear strength value.
The results reveled that the base material thickness influences the significance of the investigated process parameters / influence factors with impact onto the maximum obtainable shear strength values.
Thus, for the 0.6mm thick AHSS, the travel speed is the most important influence factor, for the 0.8mm thick AHSS it remains the most important influence factor but also the joint gap becomes important and for the 1.2mm thick AHSS, the joint gap becomes the most important influence factor.

But AlON ceramics still have many shortcomings, such as relatively low mechanical properties and low-temperature decomposition, which to a great extent limited the extension of its application in industry [7, 8].

Effect of SiC content on mechanical properties of multiphase materials.
The composite could get best properties when the content of added SiC was 8%.

Much research has been done on pipe property changing with time or temperature.
Florida Department of Transportation initiated a study on the long-term properties of corrugated HDPE pipes with consideration of temperature effect [8–11].
In this paper, both properties of HDPE pipe were investigated with FEM method.
Background Property of Pipe.
The temperature changes of buried pipe will affect HDPE pipe property, which was described in section 2.1.

Bone Regenerative Systems: Biomolecules, Cells and Biomaterials Whenever harmed, bones have the uncommon property of endogenous self-repair by recovering new bone without shaping a fibrotic scar that would adjust their mechanical qualities [7].
The most considered osteogenic factors are individuals from the changing development factor-β (TGF-β) superfamily, and basically bone morphogenetic proteins (BMPs) [10].
In spite of the fact that collagen platforms are in essence profoundly hydrated (with over 95% w/v liquid) with feeble mechanical properties for tissue substitution applications [22], the "basic" plastic pressure of the material quickly builds the relative collagen fibrillar thickness (to over 10% in weight) by evacuating the overabundance of liquid [23].

Introduction Texture structured ceramics have attracted increasing attentions because of their improved properties compared with random ceramics.
It is reported that the template particles in the range of 5-50μm have been successfully used to fabricate textured ceramics; and enhanced anisotropic properties of so-synthesized textured ceramics, mimic the properties of single crystals of the same composition, can be obtained[7].
SrBi4Ti4O15/BaBi4Ti4O15 graded ferroelectric thin films prepared by sol-gel technique was also reported and the annealing conditions affected its optical properties greatly[13].
As mentioned above, although some investigations on the preparation of BBT have been published, the factors affecting the preparation of BBT templates are not mentioned explicitly.
It was well known in single crystal growth that the morphology of crystal is determined by two factors: (a) the crystalline habit and (b) the driving force for grain growth[16].

Once the parameters are optimised, these are taken to manufacture walls of 150x150x10mm from which specimens for mechanical characterization are extracted, using EDM (Electrical Discharge Machining).
A set of tensile tests have been conducted to evaluate the mechanical properties of the SS316L and INC718 alloys.
Regarding tensile strength, the heat treatments had a positive impact on the mechanical properties, which is ideal for applications such as aircraft landing gear.

Also, because of its good properties of thermal conductivity, being non-magnetic and reflection ability, aluminum alloy sheets have a wide range of application in electronics and medical devices.
Tekaslan et al. have studied the factors such as sheet thickness, holding time and material that affect the spring-back through experiment [5].
The mechanical property of the material is shown as Table 1.

Melting characteristics of the feedstock under sole influence of heat are considered, covering a wide range of microstructural and microchemical factors, believed to be of importance at high temperatures.
The generation of the thixotropic slurry within the injection molding system and its solidification behaviour are accompanied by detailed features of the molded structures and their correlation with properties of net-shape components.
An important factor which also affects this application is shape.
The high integrity structures, with fine grains, generated after nearliquidus molding, result in properties superiour to conventional casting and to other methods of semisolid molding (Fig. 3).
These factors are vital for semisolid processing since it operates at certain solid content and does not allow for the compensation of potential heat losses using melt overheating.

These defects have a significant effect on the mechanical properties of the material and can act as failure initiation points.
Dreumel and Kamp [6] investigated the effect of fiber waviness on the mechanical properties of CFRP and found that fiber kinking did not affect the tensile modulus of unidirectional CFRP, but resulted in a 20 percent loss in tensile strength.
Residual stresses resulting from the cure or processing cycle may be responsible for localized matrix cracking, either in the matrix or the fiber-matrix interphase region [7].Incorrect temperature-time cycles, chemical inconsistency and poor mixing are clearly factors.
The effect of such damage on the mechanical properties can be significant.
Voiding gives, perhaps, the greatest cause for concern since it is common to many components and has a serious effect on certain fundamental mechanical properties.
