Dissimilar means that the metallurgical and mechanical-technological as well as chemical and physical properties of the materials differ [5,6].
The resulting temperature-gradient mechanism can lead to thermal-induced residual stresses, which can negatively affect the mechanical properties and lead to distortion [16,22].
Table 3 shows microscopy images and the surface properties of the build plates made of Titanium Grade 2 and AlMgSi0.5.
In each case, this decrease is due to favorable spatter and oxide formation, resulting in a decrease in mechanical properties due to adhesion and embrittlement.

Six Portuguese magmatic ornamental stones were submitted to Soxhlet experiments during 10,000 hours (approximately 416 days) in order to evaluate how the rain water affects the rock behavior as a dimension stone.
They also allow the identification of the way that factors like mineralogy, texture, original state of degradation, climate condition and atmospheric pollutants contribute to mineral instability, and thus may change the physical characteristics and mechanical properties of rocks.

Solution, Cantilever Beam.
However, the internal stress generated in the plated film during deposition becomes an important factor for the detachment of the thin film from the substrate.
It was found that the internal stress changed greatly in the early stages of the plating and the additive greatly affected the initial internal stress.
The angle between the reference light and object light affects the measurement accuracy because the resolution of the CCD camera is far lower than that of a conventional holographic plate.
The properties of the substrate material are shown in Table 1.

The critical factor of hardware reliability is time, which can be affected by the process of design, manufacture, and service.
Nevertheless, source code is the critical factor of software reliability.
As for embedded software, the fault of the interface between hardware and software is a major factor resulting in failure [2].
Hence, software reliability seriously affects the reliability of the whole system.
When feel pressured for product release time, reliability is always the first property to be compressed

The drilling process of these material stacks is partially very complex due to the different material properties and requirements regarding process parameters and cutting material.
Introduction Fiber-metal compound materials provide excellent mechanical properties which make them a major choice in lightweight applications [1].
Because of the different material properties the machining process of serial stacks imposes high demands to the cutting tools and requires certain process strategies [4].
Because of the anisotropic and inhomogeneous material properties this is particularly an issue in the CFRP material layer.
Due to the ductile material properties the chip is getting stretched to a certain strain limit until it finally breaks away from the workpiece.

Some of the more recent methods and tests [29-33] were further reviewed in a study by Figuera et al. [3], in which they stated that ASR and its treatment are influenced by more factors that are still unfound in literature.
This study investigates the prevention and proliferation of ASR before and after the mortars are introduced to external trigger factors like moisture and high temperature.

Introduction
Over the past few years, the sulfide-containing polymers have a rapid development due to their interesting properties [1-4].
The key factors can be determined just using the minimum number of designed experiments and accordingly, the optimal process parameters can be much conveniently gained.
Based on our preliminary study, effects of three factors (reaction temperature, reaction time and monomer concentration) on the synthesis of PPSOESE were investigated by Box-Behnken design (BBD) [27] in a fixed monomer ratio and DMAc solvent.
Also, Yield response is affected by time • monomer concentration interaction (BC, 5.39%).
The significant factors A, B, AC and BC appear positive effects.

In this case the updating parameters used in state 1 must not only reflect
the structural properties due to damage but also due to other modelling uncertainties.
The difference comes in by weighting the second row of eq.(8) by a factor ws.
The weighting factor ws plays the role of reducing the influence of the response sums.
Details of the element properties which are similar to those of the NASTRAN® Element QUADR can be found in [10].
This value was calibrated by a factor of 3.1 in order to match the measured fundamental frequency of the undamaged beam.

Although pure Mg metal is seldom employed directly as a structural material because of its poor mechanical properties and corrosion resistance, it’s still important to investigate it because it is the matrix to form all the Mg-based alloys.
A number of factors were considered to be responsible for the porosity[2].
In addition, associated with the inherent inhomogeneity of electric and chemical properties of metal substrate, neither NOF nor the ceramic coating formed at any moment was absolutely uniform in thickness and microstructure.
It’s noticeable that some other factors including standard equilibrium potentials of electrode reactions involved, polarization effects and solution resistance, etc, also exerted influences upon the voltage transient.
Its thickness increased with oxidizing time before it was affected by dielectric breakdown[11].
