Besides that, the depth of the location also affects the tensile properties of the meniscus since the structure of collagen fibers forming the meniscus has some orientation [1].
Collagens are part of the ECM and take responsibility for density and orientation in a scaffold's mechanical properties.
Silk scaffolds showed outstanding mechanical properties, biocompatibility, and versatile processability in meniscus tissue engineering.

Coupling among heat, moisture, and mechanical deformations is solved based on finite element method.
The frost depths and deformations also the porosity in consideration of the orthotropic properties of frozen soil is discussed.
Method of numerical solution It is assumed that the response of the soil to loads is elastic (total stress analysis), and the elastic properties depend on the temperature.
These results are consistent with the fact that freezing speed significantly affects the frost heave amount.
(2)The porosity character is nonuniform distribution along the soil column, the temperature gradient is one of primary factor affected the porosity rate.

Finally, the
optical properties such as focal length of developed micro-lens will be measured and tested.
To discuss above described parameters that will affect the micro-lens forming mechanism.
The reason to select PMMA as micro-lens material is that the material is very suitable for optical devices because of physical properties, optical properties and ability for IR coating.
AZ4620 will show colloid property when the temperature above Tg.
The reflow process affects the photoresist column shape, thus we discuss the reflowed diameter under various heating temperature and reflow period .In this study, the micro-lens array with high fill-factor have been fabricated, it can improve the brightness and diffuseness.

Keywords: plasma spraying; forming; particle; in-flight behavior.
Introduction Plasma spraying is a process to material coating and forming, in which a large number of factors influence the coating and forming properties.
The influence factors include the adjustable spray parameters (such as the flow rate of gas, electrical current, etc.) and the nonadjustable noise factors like the wear of the electrodes [1-3].
The main factors influencing the temperature and velocity of the in-flight particle were discussed, and then the molten state of particle was analyzed.
The experimental results show that the input parameters (gas flow rate and electrical current) mainly influence the particle in-flight behavior, which directly affects the coating quality.

However, the wettability of TiC phase and metallic binder phase is poor, leading to low density and high porosity of the sintered alloy, which seriously affects its mechanical properties and operational performance.
Mechanical properties of the alloy.
In fact, the factors affecting the toughness of the alloy are not only the mean grain size, but also composition, microstructure, bonding phase and density, and so on.

This requires a multidisciplinary approach and broad
knowledge of disciplines spanning from biology and plant anatomy to mechanical properties and
statistics.
The method can be used to detect interior defects or deterioration of wood and is used to make inferences on mechanical properties.
Since the dielectric constant of wood depends, among other factors, on wood density and moisture contents (given constant temperature and frequency), these two quantities must be measured or estimated and their variation will affect the GPR measurements.

Classical physics blending modes and effect analysis
Main factors that affect LDPE/CaCO3 blending effect are generally as follows: superposition of vibration frequency and amplitude when blending, [3] mixing ratio of LDPE and CaCO3, kinds of additives test etc.
He studied mechanical properties by scanning electron microscope to observe dispersion of nanometer ZnO particles in LDPE matrix. [9] Results prove that additives of modified nanometer ZnO can improve mechanical properties of LDPE.
Sample performances were tested in three aspects: Tensile mechanical properties, impact mechanical properties and bending tensile impact.
Compared to other related research, H.Y Wang studied mechanical properties and rheological properties during the process CaCO3 filling LDPE with titanate coupling agent activated.[17]His group found that impact strength and breaking elongation are greatly improved after activation of CaCO3, leading to better performance of mechanical properties and processablity significantly.

Multi component metallic powder is tested for mechanical properties to suit rapid tooling plastic injection moulding applications [3].
The process parameters control the mechanical properties of the parts produced by DMLS [5].
From the initial studies it was found that a few process parameters did not have any effect on the mechanical properties of DMLS components.
An orthogonal array with the five factors is shown below.
These factors determine the route of the laser beam.
