The cross-linking Ethylene-vinyl acetate copolymer (EVA) foam material is non-toxic and it has good properties [10].
The measurement of rheological properties of polymeric materials under molten state is crucial to gain a fundamental understanding of the nature of the processability for polymers.
It relates with several factors such as the weight of filler, the strength of cells, the size and size distribution of cells and the proportion of closed cells, etc.
And from SEM experiments, it also confirmed that the properties of foam were affected by cells structure which influenced by the content of poplar wood powders.
The foam has good properties when AC foaming agent was 11 wt%, DCP cross-linking agent was 0.9 wt%.

The advent of nanostructured materials and the need to design microelectronic and micromechanical devices with length scales of nanometers require not only a profound understanding, but also a reliable prediction of mechanical properties of such structures.
From the comparison of the model results with experimental data we can conclude on the importance of the different influence factors on creep in thin films. 2 Discrete dislocation model A model of diffusional creep in a thin film geometry with a single grain boundary is set up here.
In the present work we have restricted ourselves to the case where the elastic properties of film and substrate are identical, which is a very good approximation for a copper film on a silicon substrate.

These values mimic material properties of copper.

Figure 7 Relationship between factor a and b by varying nominal shear strain (1>g>0.2) and tracking angle a= p b +a0 (2) Here, the proportional coefficient p was approximately 0.054 when assuming a0 = 0.
The exponential coefficient –p appears to be varied with several mechanical or materials properties.
It was found that the tracking bending moment resistance at a certain large angle (e.g., Q=90 °) was remarkably affected by the rubbering condition.

The different flow patterns not only affect the mechanical relationship between the two phases, but also affect the heat and mass transfer characteristics [1,2].
To nuclear power, for example, a core of the reactor safety is the heat transfer control, and an important factor of the heat transfer control is the flow pattern judgment.
Many factors have influence on the flow pattern, such as the flow direction, pipe diameter, void fraction and fluid properties [3].

SiGe crystals [3] and Si/SiGe heterostructures [4] open a broad field for engineering of electronic and phononic spectra, lifetimes of localized electronic states, mechanical properties of these media.
This factor minimized impurity broadening, so that the effect of the germanium content on the donor emission efficiency could be studied.
Thus, in the case of superlattices, phosphor donor centers were not affected by strain, but may undergo stronger interaction with neighboring donors, because of the large doping concentration (NP ≈ 10 17 cm-3).
The intensity of the THz photoluminescence on Ge:Ga detector was a factor 5-7 less than the spontaneous emission observed from similar Si:P single crystals, which hade the same size and doping level.
This may affect the depletion rate of the lower level, 1s(T), in the emitter scheme.

The inevitable working medium pollution, wear and tear between components matching surface, seal own aging and other factors in the process of the operation of the hydraulic system will lead to failure of seal ring.
Engineering practice shows that the main influence factors that affect the sealing ability and lead to seal failure include working medium pressure, pre squeeze rate, the sealing groove notch radius and the temperature.
According to the material properties of the O-ring, the paper chooses two parameters in Mooney - Rivlin strain energy function model that is currently widely used in analysis to describe sealing material.

Spectral Elements for Flat Shells The spectral element discretization based upon quadrangular elements is quite similar to classical FE in many points, but a few variations in construction result in significantly improved element properties.

The solution was kept at 0℃ for 2h with vigorous mechanical agitation.
Photoresponsive behavior of ABAPE solution Thermo-optic coefficient (dn/dT) is the variation of refractive index depended on the temperature and is the main factors to affect the driver power and response speed of the optical switch.

Introduction SHM of plate-like structures can be performed using GW-based methods, however many factors, like location of sensors/actuators, sensor electronic system design, sensor shape, frequency range of excitation waves and applied signal processing algorithms affect the performance of the system [1].
Another critical factor is transducers’ distribution over the investigated plate.
The main advantage of the algorithm is its robustness [3], however it requires precise information on material properties and the thickness of the investigated structure which may be unavailable.
The advantage of this approach is that not only damage-reflected waves can be used as damage symptoms but also reflections from the structural elements affected by the damage can be seen in the differential image.

The main factors for the rejections were due to their inadequate anthropomorphic characters: 1) Heavy weight; 2) Few DOFs which could only realize simple grasp; 3) The appearance far from human hand; 4) Limited controllability: due to the lack of sensory feedback, the actuation system and the number of active/controllable degrees of freedom[9,10].
Using the virtual prototype, mechanical features of each component were iteratively modified and verified.
Using this control scheme we would be able to control the complete impedance property of a finger: (3) where , and are the desired target impedance parameters of the finger.
However, in reality, the finger dynamics is not known precisely, and the accuracy of the position and torque sensors are always affected by some noises.
Dynamic control can make the finger grasp with more smooth and precise trajectory and stable grasp force, in other words more like human grasp than mechanical grasp.
