Subsequently, the three point bending technique was carried out to obtain the micromechanical properties of semiconductor package.
Ionization initiates physical changes of irradiated material that may potentially affect its electrical, chemical and mechanical properties [1].
Irradiated to gamma radiation was altered the mechanical properties of QFN package [1].
Thus, the condition may lead to the factor of extended plastic deformation affected.
From the results above, it can be believed that exposure to gamma rays has a significant effect on the mechanical properties of QFN package.

However, the researchers are interested in using lithium oxide (Li2O), since Li2O has the same chemical properties as Na2O and K2O, but it is a stronger fluxing agent.
For glazes of willemite crystals, there are several factors for the crystallization that must be controlled [5-6], including the uniformity of used raw materials, the fineness of grinding glaze slip, the density of glaze slip, the viscosity of the glaze slip at high temperatures, the thickness of glaze layers applied on biscuit, the formula of clay body used, the temperature for firing and the duration of soaking time [7].
Mechanical property of willemite crystal glazes will be measured by Vickers hardness testing machine.
Mechanical property.
The Li2O content affected microhardness value in the glazes.

A constitutive equation for viscosity is formulated which considers all factors affecting viscosity with the maximum percentage error of about 4% between experimental value and value predicted by the formulated equation is obtained.
Hence it is primarily important to study and formulate a common constitutive equation characterizing the effect of various parameters affecting the viscosity of the feedstock.
On considering all the facts mentioned in the section on rheological properties, a single equation which combines all parameters affecting viscosity of composite, can be established.

SECURING SUPERIOR PROPERTIES OF COMPOSITE (PP+ WF) THROUGH CENTRAL COMPOSITE DESIGN A.
Due to numerous attractive properties, use of composites is in increasing trend.
The purpose of this project is to optimize the mechanical properties of composite (polypropylene + wood fiber) using Central Composite Design (CCD) technique.
The values of the coded variables can be obtained with following transformation: Coded Variable = lnXi – ln(central) ln(max) – ln(central) Figure 1: Geometric representation of CCD with 3 factors The coded variable allows an experimenter to investigate the relative importance of the design factors or parameters.
Hence a superior composite in terms of mechanical properties is possible to be attained by optimization of the three processing parameters through RSM and the derived models can be reliably used to predict the functional properties of the composite in terms of the processing parameters at least within experimental limits.

The quality of the aggregates also significantly affects concrete properties; therefore, the use of recycled aggregates is mostly not recommended in HPC design, due to their high absorption capacity, unstable properties and weak strength [7].

Asim et al. [2] reported that PALF shows superiority in terms of its mechanical properties over other plant-based fibers.
Based on Table 2, only the interaction (p-value = 0.001) between the two factors has a significant effect on the mechanical response.
Only the interaction between the two factors significantly affects the tensile strength perpendicular to the surface.
Only the interaction between the two factors significantly affects the flexural strength.
Results showed that not all mechanical properties of the composites could be improved simultaneously.

Processibility and mechanical properties of mullite-filled styrene butadiene rubber composites Qiongqiong Liu　 Department of Materials and Engineering, Xuzhou College of Industrial Technology, Xuzhou, Jiangsu, China 　eliuqq@163.com　 Keywords: mullite, SBR materials, fillers, cure characteristics, mechanical properties Abstract.
The presence of the silane coupling agent can enhance mechanical properties of filled SBR vulcanizates to some extent.
The properties of the compounds (cure characteristics, processability) and mechanical properties of vulcanizates with various filler loadings were investigated.
Mechanical properties of SBR vulcanizates The mechanical properties of filled rubbers are usually described in terms of tensile and tear strength, Young’s modulus, hardness, resilience and abrasive loss.
Silica provides better mechanical properties than mullite

The corresponding prevention measures to different influencing factors were presented in the end.
Mechanical Analysis on the Substructure Stability due to Landslides and Mudslides Bridge pile foundation general would not directly influenced by external force, but if bridge pier was affected by an external force such as landslide thrust, the internal force of pile foundation inevitably increase.
Fig.1 Typical section of bridge pier column Fig.2 Pier column’s force diagram impacted by landslide thrust and debris flow pressure Usually, landslide affects pier on one side, but debris flow had fluid properties, so it affects the pier on both sides, the bending moment diagram of pier subjected to two kinds of external force as shown in Fig.3.
The lack of soil around the pile which caused by soil erosion could be an important factor affecting the pile safety, shown in Fig.4.
The bearing characteristics, internal forces, displacements and other characteristics of the pile were influenced by the degree of soil erosion around the pile, the properties of soil around the pile, the material and size of the pile and other various complex factors.

Using the mechanical equivalent of heat (M ), the rate of specific volumetric flux is: (2) Of course, all mechanical and thermal material properties can be temperature dependent.
