The main factors of the delamination are thermal stress, hygrostress and vapor pressure.
The material properties needed for moisture diffusion study are D and Csat.
In the present work the material properties are shown in Table 2 [12].
These results accord with the material properties for moisture diffusion (Table 2).
Therefore, the delamination seriously affects the using life and reliability of package.

The gel-forming properties are strongly correlated with the proportion and length of the blocks of contiguous L-guluronic acid residues (G-blocks) in the polymeric chains [2].
Major factors affecting CDHAp/Ca-alginate bead shape were: the concentration of Na-alginate, the concentration of Ca2+ and a choice of a solvent.

This paper presents a 3D coupled thermo-mechanical finite element model based on ABAQUS\Explicit for the simulation of Inconel 718 chip formation in metal cutting.
Introduction Inconel 718 is widely used in many industries, owing to its unique properties such as high oxidation resistance, corrosion resistance even at very high temperatures and retains a high mechanical strength under these conditions.
Indeed, to get an efficient correlation between simulations and experiments, it is necessary to have an accurate prediction of material behavior and a proper contact/friction defines at the interfaces and a precise tool model. 2.1 Material constitutive model The accuracy of the finite element analysis is severely dependent on the accuracy of the material mechanical properties.
Material properties, e.g. stress-strain relationship, are affected by the strain rate and temperature during material forming process with plastic deformation.
The Abaqus/explicit code was inability to predict the correct chip morphology due to a number of factors.

Due to its stochastic properties, study of deposition process can be done by using a simulation based on a Monte-Carlo method [1,2].
The structure of the deposited material determines the properties of the film, including its mechanical strength.
Porosity is one factor that affects physical properties of the material [3] and can be used to assess the mechanical strength of the material.
By using a granular method, each cluster of particle could have different properties, so a deposition process of multiple types of particle can be obtained.
Xia, Porosity dependence of mechanical properties of solid materials.

These alloys are recognized to be highly cost effective and combine good corrosion properties and formability with moderate strength.
The last two properties are mainly controlled by the grain structure/size in the material and show opposite trends with increasing grain size: mechanical strength decreases whereas the material becomes less subject to corrosion.
Depending on the targeted applications a compromise between these two properties has to be made by controlling the softening behavior.
Then the interfacial concentrations must fulfill the following solubility products [4]: (4) The is the Gibbs-Thomson factor that describes the influence of precipitate curvature on interfacial concentrations.
The grain size, however, is barely not affected in these particular cases, as site saturation is assumed and concurrent precipitation only influence growth.

The continuous indentation technique is widely used for nondestructive evaluation of the mechanical properties of devices and materials.
Through analysis of this curve, various mechanical properties, such as flow properties, residual stress, fracture properties, viscoelastic properties, hardness, etc., can be evaluated.
However, work is ongoing to evaluate other mechanical properties such as fracture toughness [3,4], flow properties [5,6], viscoelastic properties [7,8] and residual stress [9,10].
Evaluation of Indentation Flow Properties.
Indentation flow properties are the properties obtained from analysis of the indentation load-depth curve.

Micro-mechanical and tribological properties as well as coating adhesion to the substrates were investigated.
Properties arise from their specific structure where hard nanocrystallites nc-MX are placed in a softer, amorphous matrix.
To provide advantageous mechanical properties of the coatings, nanoparticle size should not exceed 5 nm, and the distance between their boundaries (the thickness of the matrix material) should not be too large (within 1÷2 nm [8,16,17]).
Amorphous carbon (a-C) is well known material characterized by excellent tribological properties [18-20].
Such low friction coefficient is due to excellent tribological properties of amorphous carbon matrix.

While improving the machining rates will go a long way towards increasing the usage of the material, it must be noted that this is only one of the number of factors affecting the use of the material.
Zoya and Krishnamurthy [24] have discussed the factors that affect the machining of titanium and its alloys.
Shane et al [26] have reported how the temperature affects Ti-64 alloy properties and they have proposed a new economical cryogenic cooling approach.
It is interesting to note the good mechanical properties of the titanium alloys with respect to steel but relatively poor thermal properties (Machining Hand Book [56] and Materials Properties Hand Book [57]).
Cutting temperature has been recognized as an important factor affecting the tool wear rate and tool life.

Power lines and tower attachments long-term effected by mechanical tension, electrical flashover, and material aging, will produce off shares, wear, corrosion and other damage; in addition, the trees growth around the EHV transmission lines running area will lead to the width of safe passage not enough; above elements if not promptly treated and repaired, will lead to serious accidents, brings great risks to the power transmission.
Because of the special nature of the use of regional environment, UAV flight attitude diversifications, spindle vibration, air resistance and other factors, the overall structure of the pod requires sufficient strength.
The main alloy element of material is zinc, and the intensity of material can reach 572Mpa.This material has good mechanical properties and heat treatment properties, and has been widely used in the aerospace field.
Continuous vibration of UAV will affect the stability of the pod system optical visual axis, this needs higher requirements on the structural strength of the pod system.

Introduction Boring axle is one of the important components of NC boring and milling machine, its working conditions directly affect the machining performances and processing quality of parts.
In addition to the above machining requirements of each surface, quality control and selection, heat treatment of material are also researched in order to improve integrated mechanical properties of parts.
Technical Design of Boring Axle Processing Because the boring axle often works in high-speed, high-torque condition, and the boring axle suffers alternating stress, the boring axle must have properties of good wear resistance and higher fatigue.
