Many scientists [10,11,12,13,14,15] have studied the factors influencing the energy scavenging from the DEAP property.
For strains up to this maximum value the Mooney-Rivlin model is used to describe the viscoelastic properties of the DEAP material[22].
So that any contraction in the material thickness (direction) due to the electrostatic forces is converted into an elongation in the length direction (direction), For strains up to this maximum value the Mooney-Rivlin is used to describe the hyperelastic properties of the material.

Thickness and temperature of SRM were two important factors influencing the permeation proportion of DMMP.
However, previous studies found that fumed silica mostly aggregated in the silicone rubber which influenced the mechanical property.
If P, Am, H, Fc are settled factors, the ratio of PI and Px was positive correlation to the permeability coefficient of the membrane (Pr).
Temperature of SRM was an important factor to permeability of SRM.
In conclusion, our results demonstrate that the PDMS/silica mixed matrix membrane with thickness not more than 10 μm possess desirable properties that can meet the essential requirement for sample inlet membranes of ion mobility spectrometers.

Analysis of Junction Temperature of AlGaInP LED Song-Feng Wan, Ching-Yen Hoa*, Yong-Gang Chen, Qing-Bin Li and Fa-Fen Yao Department of Mechanical and Electrical Engineering, Dongguan Polytechnic, Dongguan 523808, China a*hcy2182@yahoo.com.tw Keywords: AlGaInP, LED, Temperature Abstract.
Based on the material properties of AlGaInP LED, this paper proposes an approach for predicting the junction temperature.
It not only affects the photoelectric conversion efficiency and lifetime of the LED [1-3], but also significantly affects its operating characteristics [4,5].
This article analyzes the junction temperature of AlGaInP LEDs using Shockley's equation, Ohm's law, Fourier's law, and material properties of LEDs.
The influences of working parameters and material properties on the junction temperature are discussed.

The study provided a new insight into the contribution of heat input rate in the production of unwanted weld microstructural features and assisted in the design of methods and techniques for tailoring weld microstructures with optimum properties.
The weld section microstructure is influenced by the heating and cooling conditions during welding in terms of the weld heat input per unit length and the energy transfer factors which are governed by the welding current, welding speed, the degree of dilution and the materials property.
For instance, Reddy and Meshram [4], reported that grain size reduction in weld section of structural steels confer the advantage of increased resistance to solidification cracking and improved mechanical property.

Properties of the binder matrix affect the quality of the refractory.
For the most type of refractories, structural properties depend on the properties of binder matrix.
Discussion of the Test Results Samples, which were prepared from KA type binder, showed better mechanical properties than samples from QA type binder, higher compressive strength, cold bending strength and hot modulus of rupture.
For the Q/A samples, appareant porosity is found to be an important factor for the determination of creep properties.
It was found that; ZrSiO4 addition in the binder mixture improves the densification behaviour, mechanical properties and reduces the high temperature creep rate at 1500 °C and reduces the slag infiltration depth.

The GMA is placed in a closed internal space relatively, and heat dissipation of the system will cause thermal deformation, having a great impact on the stretching the properties of the giant magnetostrictive materials and the implementation of the output precision seriously with magnetostrictive materials of nonlinear properties.

Introduction The grain boundary (GB) is the area where numerous phase transformations easily occur, leading to dramatic changes on the mechanical and physical properties of polycrystalline materials [1,2].
The presence of premelting significantly affects the strength and fracture properties of polycrystalline materials.
Heating rate is an important factor of the GB premelting.

Fatigue life is the common damage style for coil spring, many investigations performed on materials to improve the mechanical properties of materials.
The research on VHFC indicates that the various spring types in test exhibit different fatigue properties and also different failure mechanisms in the VHCF regime[6].
Both element type and element size all affect the accuracy and stability, so a higher order 3-D 20-node solid element type is used which can exhibit quadratic displacement behavior.
Furthermore, the usage safety factor derived is 1.335 which is within the allowable safety factor range, so the fatigue life also can satisfy the requirement for utilization.
The fatigue life of the valve spring is calculated according to the shear stress, the derived safety factor is within allowable safety factor range, which indicates that the valve spring could not damage under actual working condition.
