Sun et al. studied the influence of the surface quality on the mechanical properties of the AMed Ti-6Al-4V [5].
Therefore, an AMed part has the microstructural characteristics and thus mechanical properties different than that of the castings and forgings [10].
Different processes could cause different mechanical properties of the material, as shown in Table 1.

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%.

It integrates into one single complex seismological, economic, technical and sociological factors that affect optimal decision making about economic costs taking into account the degree of inevitable risk for structures.
Thus, economic analysis in quake proof construction requires quantitative assessment of three essential factors: · additional investments in construction of quake proof facilities; · amount of direct and indirect financial losses as a result of structural damages in potential earthquakes; · risk of human lives loss in money terms.
It also allowed to assess changes in stiffness properties of the materials.
High reliability of the system can be provided solely with technical measures that do not result in large expenditures, while the optimum reliability criterion is not affected by cost restraints and so optimization is done according to the principle of maximum reliability (6) Optimum parameters of reliability must be allowable and strongly valid taking into account economic and social factors.

Abstract: In most coating applications damage resistance is controlled by the mechanical properties of the coating, interface and substrate.
For electronic and optical applications the design of coating-substrate systems has been predominantly controlled by their functional properties but more recently the mechanical response of the system has been used to enhance functional properties, as in the case of strained silicon/SiGe microelectronic devices where tensile strain has been used to enhance mobility and increase device speed.
Finally the mechanical design of a metallization stress sensor based on nanoindentation-derived materials properties, non-linear elastic and plastic behavior and the treatment of geometrical non-linearities (stress stiffening) is discussed. 1.
Conclusions Finite element simulations can be used to assess the nanoindentation response of nanostructured multilayer thin films provided that scale-dependent mechanical properties are used.
For single layer metal coatings which are polycrystalline a strong indentation size effect is observed and the scaledependence of mechanical properties is significant.

Besides the desired properties of the obtained sorption material (mechanical strength, porosity, specific surface area, the chemical nature of the surface) technological factors and characteristics of the cleaning solution affect the sorption.
For this reason, the determination of physico-chemical properties of the newsorption material is necessary.
The equilibrium concentration of zinc ion in solution, mg/l A systematic analysis showed (Fig. 1) that an increase in the specific surface area of the sorption material increases its adsorption properties.
Effect of temperature on the adsorption capacity of solutions sorption material The work investigated the effect of pH on the properties of the resulting composite.

Introduction Strength properties of concrete are very important for designing a structure and these properties depend upon the ingredients of concrete [1].
Flexural strength is one of the important properties of concrete as it affects shear strength deflection, brittleness ratio, and flexural cracking of concrete and is also known as modulus of rupture [22].

Introduction Fabrication of ultra-fine grained (UFG) metallic materials by applying severe plastic deformation (SPD) is currently of a great scientific interest due to their unusual mechanical properties [1].
Therefore, in order to understand better the essential details of deformation, the effectiveness and influencing factors on grain refinement of GP, and distinguish between CGP and UGP, the authors here try to study systematically the deformation behavior, microstructure evolution and mechanical properties of a 5052 Al alloy deformed in CGP and UGP by adopting three-dimensional finite element simulation (3D FES) combined with experimental investigations.
The properties of 5052 Al alloy were described by , where σ was the flow stress, ε the strain, the strain rate and T the temperature.
Consequently, there might be instabilities in microstructures and properties within these zones.
Conclusions The deformation behavior, microstructure and mechanical properties of a 5052 Al alloy deformed in CGP and UGP were investigated by adopting a 3D FES combined with experiments in this paper.
