Since there is a considerable scatter in the data, a reduction factor is often applied to the S-N curves to provide conservative values for the design of components.
Of course, environmental conditions, load history, statistical aspects, and safety factors must be incorporated in this methodology for remaining fatigue life assessment.
After idealizing the detected defection, relevant stress intensity factor will be gained via calculation or fatigue handbook.
Furthermore, material properties such as young modulus, tensile strength, yield strength and fracture tough and so on can be obtained via tests.

The extensive applications of epoxy resins motivate the preparation of organic/ inorganic composites of epoxy resins with better properties and applications.
However, they are frequently subjected to severe environmental conditions, making improvements of its mechanical and thermal properties more desirable (Ahmad et al., 2010).
The moisture effect is interesting to be investigated since the presence of water can affect the chemical and physical properties of epoxy resins.
Temperature plays an important factor in dynamic modelling.

The definition of food texture has been stated as “the sensory and functional manifestation of the structural, mechanical, and surface properties of foods detected through the senses of vision, hearing, touch and kinesthetics”[1].
It could be concluded that the degradation in the myofibrillar protein of red sea bream muscle affected its texture during the storage in accordance with the resilience.
The factor analyses with the principal components method were shown in Table 3. 46.13% of the variance was explained by factor 1, while factor 2 explained 41.34%.

These factors are also disadvantages of microwave heating.
Additives must be conductive or have dielectric properties that are significantly different from the polymer matrix [7, 8].
Improvement in properties can be achieved by improving the quality of distribution of modifying additives during processing.
The aim of this work is to study the possibility of improving the properties of non-polar polymers by carbon nanotubes that absorb microwave waves.

Discoloration of resin composites may be caused by intrinsic and extrinsic factors.
Intrinsic factors such as incomplete polymerization, initiators, fillers, and pigments can affect the color stability of resin composite [5-6].
Extrinsic factors such as absorption of stains from foods and drinks may also cause discoloration [7-8].
However, the effects of bleaching agent on physical properties of materials are issues that the dentists should concern since the contact with bleaching agents can cause superficial degradation of resin composites, affecting roughness, hardness, and gloss [25].
Review of research on the mechanical properties of the human tooth.

This study involved six factors of comfort which is air temperature, average radiant temperature, air velocity, relative humidity, metabolic rate and clothes insulation.
Although the biological properties of each people are different, but there is an optimum degree of thermal comfort, where the percentage is in thermal comfort was the highest.
The course of work and labor productivity will be affected when employee had uncomfortable environment.
The following annoying and/or harmful work environment factors can occur in the workplace such as: chemical, biological or dust pollutants, noise, mechanical vibrations, electromagnetic field, static electricity, improper lighting and microclimate [7].
This is because of different weather factors that influence data collected.

Although the effect of the reinforcing phase on the mechanical properties of the amorphous matrix at room temperature has been extensively studied in recent years [7], little attention has been given to the deformation of BMG composites in the supercooled liquid region.
There exist various models to elucidate the mechanical deformation behavior at high temperature of amorphous alloy.
The pre-exponential factor 0ε& ranges from 1x10 -3s-1 to 3x10 -3s-1.
Larger initial void size (or, equivalently, a larger initial void fraction) can weaken the mechanical properties of the BMG composite.

SEM photos show the surface shape of the material with varied indentations and protrusions. 2.6 Mechanical properties DMA analysis determines the mechanical and viscoelastic properties of a membrane.
These results are consistent with the desired properties of the hemodialysis membrane, namely that the inner surface has the smallest pores to prevent solute blockage [12]. 3.1.2 Mechanical properties DMA analysis to determine the stress and strain capability of existing commercial hollow fiber dialyzers.
Stress can cause significant changes in membrane properties by affecting the orientation of molecules during membrane formation [13].
First, different polymer/solvent combinations have distinct effects on membrane properties.
